Scientists at other laboratories and institutions have agreed that the process works, in theory. It’s a big job, but this system is the best, and you can mix biodiesel, diesel, and SVO. This little known plugin reveals the answer. The catalyst, along with a large amount of heat and pressure, triggers a chemical reaction that forms chains of hydrocarbons. But producing them requires complex chemical conversions. The biomass is burned in a low oxygen environment to produce syngas, a step that requires less energy than other synfuels. Amazon Doesn't Want You to Know About This Plugin. Learn about a little known plugin that tells you if you're getting the best price on Amazon.

Synthetic fuels are frequently referred to as synfuels. The carbon in the coal combines with oxygen in the water to create carbon monoxide, while the leftover hydrogen atoms create hydrogen gas. However, this synthetic fuels program was halted by Congress in 1985, after spending $8 billion US Dollars (USD) over a 40 year period. "Green Freedom: A Concept of Producing Carbon-Neutral Synthetic Fuels and Chemicals (Patent Pending)." Synthetic fuels could be the answer to achieving carbon-neutral emissions in the following sectors. With synthetic fuels come the option of keeping your favourite car or motorcycle as it is and still power it in the future. Coal-to-liquids and gas-to-liquids fuels are produced by manipulating the hydrocarbons in non-oil fossil fuels so that they are chemically similar to the hydrocarbons in oil and gasoline. "Scientists Would Turn Greenhouse Gas Into Gasoline." The former use could be the most interesting, as eFuel or synthetic fuel gives ICE-based motorsport series a new way to promote a green message. Once the CO2 is separated, it is converted to syngas and then into liquid fuels following methods used to create other synfuels [source: Martin]. The GTL process in particular has mostly been used to produce diesel fuels, although it can also produce naphtha. I have an old Jetta TDI that I was planning on getting rid of, but I was thinking about converting it to run on fry grease. Shale oil is another form of syncrude produced from marlstone, a naturally occurring rock that is commonly called oil shale. As a way to make driving existing vehicles more sustainable, Porsche has been working on synthetic fuels it calls eFuels that the company says can make an … The massive amounts of water and power needed to transform oil sands from deep underground deposits to usable fuels make it a controversial fuel because of its environmental impact. Wikibuy Review: A Free Tool That Saves You Time and Money, 15 Creative Ways to Save Money That Actually Work. Waste used for feedstock undergoes the same process as other synfuel feedstocks. Ideally, this would result in a balanced CO2 balance. It will take about 15-20 hours to install, and requires some mechanical skill. Biomass takes up much more space than other synfuel feedstocks, so it costs more to store and transport. Synthetic Oil: Overview Artificially created lubricants are often used as a substitute for petroleum-based oils, which are required to operate in extreme temperatures. Bitumen is a very thick oil-like substance that is the consistency of very sticky Jell-O at room temperature. The production process for many synthetic fuels creates products that are more or less ready to be used in engines and vehicles. Seriously, synthetic fuel could be a game changer if Porsche's early projections pan out. On the bright side, the entire process is theoretically carbon neutral. They don't need to be processed by a refinery before they are used as fuel. The use of biofuels and synthetic fuels reduces the U.S. dependence on foreign oil and helps mitigate the devastating impact of increases in the price of oil, The bitumen is then subjected to huge amounts of heat and pressure, and natural gas is introduced. In fact, deposits in the Green River Formation, a region that extends through parts of Colorado, Utah and Wyoming, could contain enough oil shale to produce 800 billion to 1.8 trillion barrels, according to estimates from various scientists [source: U.S. Department of the Interior]. TO convert your vehicle, you will need to replace your fuel return lines (the ones returning fuel from the injectors to the tank) with synthetic lines. March 2002. Of course, processing requires an additional step to convert the solid coal into a gas that can feed the F-T reaction. Many synfuels also burn cleaner than conventional fuel. That sets them apart from currently available biofuels, such as ethanol, which have to be mixed with gas or require special engines. (Dec. 10, 2010)http://www.worldcoal.org/bin/pdf/original_pdf_file/coal_liquid_fuels_report(03_06_2009).pdf, 5 Alternative Fuel Ideas that Never Made it Out of the Lab. In direct coal liquefaction (DCL), coal is pulverized, and then exposed to hydrogen and high levels of heat and pressure to produce liquid syncrude that can be refined. Whatever you're using to produce the synthetic fuels, the first step is to convert it into carbon monoxide and hydrogen gas. A Carbon Engineering staff member holds clean synthetic fuel made from Carbon Engineering’s Direct … March 2009. What is eFuel? Extra-heavy Oil. He has also worked for the Matt Sailor Synthetic fuels would be an easy fit for the transportation system because they could be used directly in automobile engines and are almost identical to fuels refined from crude oil. Well, the composition is a secret for obvious reasons, but Porsche claims that their synthetic fuel has only 8-10 components whereas petrol has 30 – 40 undesirable components. Feb. 14, 2006. There may not be a magic bullet to solve that energy crisis, or a perfect fuel that is infinitely available and doesn't pollute the environment. One of the largest implementations of Fischer–Tropsch technology is in Bintulu, Malaysia. I would strongly advise that you stay away from two tank systems and use something like an elsbett single tanks system. Also, until technologies are further developed and refined, the process is extremely expensive -- much more expensive per-barrel than crude oil production [source: U.S. Energy Information Administration]. Extra-heavy oil occurs naturally, and forms when oil that was once buried deep in the Earth is exposed to bacteria that breaks down the hydrocarbons and changes the oil's physical properties. What are the economic drawbacks of using biofuels? Michael is a longtime wiseGEEK contributor who specializes in topics relating to paleontology, This Shell facility converts natural gas into low-sulfur Diesel fuels and food-grade wax. The ability to store terawatt hours (TWhs) of chemical energy economically allows the supply of primary energy to be decoupled from the demand of energy on a grand sca… On paper, they sound fantastic, with the potential to replace fossil fuels and make existing petrol and diesel cars CO2 neutral. Part of this is due to the cost and availability of fossil fuels versus other primary and secondary energy sources, but an often-overlooked reason is from the intrinsic benefit that these fuels bring. The main benefit of synfuels is that they can be produced using substances like coal, natural gas and even plant waste, which are widely available. National governments and energy companies have been paying more attention to synthetic fuels in recent years, as rising oil prices and political instability in oil-producing countries have created incentives to seek out alternatives. "Synthetic Fuels Production Process." But in situ collection consumes huge quantities of water and power and is also less cost-effective. Oil shale is extremely abundant. But it takes comparatively large quantities of biomass feedstock (the raw material that is synthesized) to make fuel. Manufacturers use two methods to make that conversion. Usable solid waste includes old tires, sewage and waste from landfills [source: Speight]. Next, the gas is condensed into liquid. National Petroleum Council. Porsche, however, is developing a new synthetic fuel which they call eFuel because this synthetic fuel can replace conventional gasoline and have benefits similar to electric vehicles. Oil sands, or tar sands, are the third source of synthetic fuels that are classified as syncrude. We also share information about your use of our site with our social media, advertising and analytics partners who may combine it with other information that you’ve provided to them or that they’ve collected from your use of their services. Particularly where motors that have seasonal use are concerned, high-quality synthetic 2-stroke oil can be useful as among the additives you’ll often find fuel stabilizer. For the next step, Carbon Engineering’s Air to Fuel technology produces synthetic, liquid transportation fuels, such as gasoline, diesel, and Jet-A. In situ methods need further research to gather large amounts of heavy oil. Another benefit is that the chemical reactions involved in converting the gas to liquids create electricity, steam and water as byproducts. Depending on which catalysts are added, different hydrocarbon structures are created. Synthetic fuel: fact and fiction Over the last week or so you might have read about ‘synthetic fuels’ that could be created from carbon dioxide and used to make existing petrol and diesel engines carbon neutral. October 2006. With oil and fossil fuel resources dwindling around the world, the race to find the next big energy solution is definitely on. Such substitutes include synthetic crude oil (syncrude), methanol (CH3 OH), ethanol (C 2 H 5 OH), and methane (CH 4). To process oil sands to a state they can be sold as syncrude, they're washed with hot water to separate the bitumen from the clay and sand. Still in the theoretical stage, the concept of deriving fuel from atmospheric CO2 was developed by scientists at Los Alamos National Laboratories. This syngas, a mixture of carbon monoxide, hydrogen and other gases, is then used in the Fischer-Tropsch reaction to create liquid fuels. Those resources can either be funneled back into the production to save costs and reduce the environmental impact or sold on the commercial market to make the process more cost effective. @ GiraffeEars- If you are converting to SVO (vegetable oil/fryer grease) you will need further modifications. Synthetic fuels, or synfuels, have been discussed for many years. Synthetic fuels are any liquid fuel manufactured from something that has energy - like coal, natural gas, tar sands, or biomass. It is burned under special conditions to produce syngas, which then goes through the Fischer-Tropsch process to be synthesized into liquid fuel. National Geographic. For climate targets to be achieved, CO₂ emissions from traffic worldwide will have to be reduced 50 percent over the next four decades, and by at least 85 percent in the advanced economies. The oil can be recovered through open pit mining or "in situ" (on site) collection. Compared to pump fuel, eFuels emit … Once the car begins to sputter at high speeds or become sluggish, change the fuel filter. Synthetic fuels, which are substitutes for oil and natural gas manufactured from coal or “biological waste”, are mainly for use as fuels for combustion engines in the transport sector. These are the only non-synthetic lines, and they will eventually corrode from running the cleaner alcoholic biodiesel. Synthetic fuels are classified based on what feedstock was used to create them. Alternative Fuels and Advanced Vehicles Data Center. United States Department of Energy. There is only one major modification and a couple of filter changes necessary to convert to biodiesel. Nearly all modern energy systems are critically dependent on fossil fuels. The major chemical difference between natural gas, crude oil, and coal is their hydrogen-to-carbon ratios. Synthetic fuel is a category of fuels that includes any fuel "produced from coal, natural gas or biomass feedstocks through chemical conversion" [source: U.S. Energy Information Administration]. (Dec. 10, 2010)http://www.afdc.energy.gov/afdc/fuels/emerging_coal_liquids.html, United States Department of Energy. Biodiesel effectively cleans all of the petrodiesel sludge out of your fuel system, causing it to collect in the filter. (Dec. 10, 2010)http://ostseis.anl.gov/guide/oilshale/, United States Department of the Interior, Bureau of Land Management. This second method is not as widely used as ICL. The sands are usually gathered through open pit mining. Now run B100 until the same thing happens again. "About Oil Shale." From there, Porsche and Siemens use captured carbon dioxide from the air, in combination with the hydrogen, to form synthesized methanol. Shell middle distillate synthesis. This produces a substance called syngas, which can itself by used as a fuel, or further processed into diesel or another derivative. It also releases carbon dioxide emissions and large amounts of solid waste called "slag," which is what's left of the coal after all of its usable chemicals have been extracted [source: Van Bibber]. 2008. Synthetic fuels are made by extracting hydrogen via renewable energy, and capturing it liquid form with carbon dioxide. Unlike syncrudes, GTL products are closer to the final stage of production. "Biomass to Liquids." It also damages the environment by destroying forests and animal habitats, and the large amounts of water required has to be disposed of as waste after being used [source: Clark]. April 9, 2007. Synthetic fuel is effectively an eco-friendly replica of petrol or diesel, with the idea that internal combustion-engined cars would be able to run as they do now on fossil fuels but cut down hugely on CO2 emissions and harmful particulate matter. To get the extra-heavy oil into a useful form, it is typically exposed to heat and gases that break down the hydrocarbons into those that can be burned as fuel and those that can't. I am mechanically inclined, so I would prefer to do this myself. Production of shale oil is largely theoretical at this point and hasn't been produced on a large scale. Change the filter one more time and you are ready to go. (Dec. 10, 2010)http://www.nytimes.com/2008/02/19/science/19carb.html, Clark, Bryan. In this process, large amounts of air containing carbon dioxide pollutants would be exposed to liquid potassium carbonate. "Coal: Liquid Fuels." Marlstone is rich in a material called kerogen, an organic material that naturally converts into crude oil when it's exposed to extreme heat and pressure. So, we now know which fuel of the future we are rooting for. I hope this helps you make the move to renewable fuels! The technology can be used to convert natural gas, biomass or coal into synthetic fuels. Daily Express Porsche said the synthetic fuel will be "cleaner" and expects an 85 percent reduction in CO2 output. A TDI is a Turbo Direct Injection Diesel, so the viscosity of the fuel plays a large part in the performance of the vehicle. But there are serious environmental drawbacks, too. Chemically, synfuels are similar to the gasoline and diesel fuels we use today and can be used in existing engines. The CO2 in the air combines with the potassium carbonate, while the other components of the air do not. You will essentially be installing new injectors, filter heaters, fuel lines, relays, coolant heat exchangers, oil temperature sensors and glow plugs. Solid coal is crushed, and then exposed to high temperature and high pressure, along with steam and oxygen, which react with the coal to produce synthesis gas. While they can burn cleaner, producing synthetic fuels often causes just as much, if not more, pollution than traditional gasoline. (Dec. 10, 2010)http://www.netl.doe.gov/energy-analyses/pubs/Baseline%20Technical%20and%20Economic%20Assessment%20of%20a%20Commercial%20S.pdf, World Coal Institute. A common conventional feedstock is natural gas, but (Dec. 10, 2010)http://www.afdc.energy.gov/afdc/fuels/emerging_gas_liquids.html, United States Department of Energy. Oil Shale & Tar Sands Programmatic Environmental Impact Statement. "Topic Paper #22: Heavy Oil." "Top 8 Synthetic Fuels" BTL also costs much more money to produce than CTL or GTL. As long as it contains organic matter (and high levels of carbon), it can be used to create some form of fuel. The Los Alamos scientists suggest nuclear power as the best option [source: Martin]. Methuselah Foundation, the Singularity Institute for Artificial Intelligence, and the Lifeboat Foundation. Shale oil production leaves large amounts of waste rock behind and uses huge amounts of water. Produced by extracting CO2 from the atmosphere in a process known as ‘direct air capture’ and combining it with hydrogen produced by renewable energy, synthetic fuel (synfuel for … Putting all these together, synthetic fuel will be too little, too late, and for too much money per mile. In addition to being an avid blogger, Michael is particularly Both methods have their limits. Chang, Kenneth. Synthetic fuels can be used in existing combustion engines without any adaptations needed, meaning cars already on the road can use the sustainably sourced fuels, while also reducing the need to bring in bans so soon. In short, any 2-stroke motor is a suitable place to use synthetic oil specially formulated for 2-stroke engines. As an alternative, the gas that landfills naturally emit as waste decomposes can be used to produce synthetic fuel. The Fischer-Tropsch process, developed by Nazi Germany and used by Sasol in South Africa today is one of the most used for converting coal, as well as biomass or natural gas, into synthetic fuels. In 1944, when the Synthetic Liquid Fuels Program was established as a program run by the US Bureau of Mines, the United States government supported the production of synthetic fuels with investment. Please copy/paste the following text to properly cite this HowStuffWorks.com article: Copyright © 2021 HowStuffWorks, a division of InfoSpace Holdings, LLC, a System1 Company. (Dec. 10, 2010)http://www.lanl.gov/news/newsbulletin/pdf/Green_Freedom_Overview.pdf. What are the economic advantages of using biofuels? The production process is similar to other synfuels: Syngas is used to start a Fischer-Tropsch reaction that eventually produces liquid fuels. A mix of water, clay, sand and a substance called bitumen, oil sands occur naturally. CTL production consumes huge amounts of water before it creates any. Biomass-to-liquids fuels work according to the same theory, except that the hydrocarbons come from freshly dead organic material, not organic material that has been decomposed and compressed over millions of years. physics, biology, astronomy, chemistry, and futurism. Diesel used to be made only by petroleum, hence it was called petrodiesel. Today, other substances such as biomass or natural gas are used to make it, hence biodiesel. In its natural state, extra-heavy oil is basically a more viscous form of crude. “Finally, there are third-generation biofuels, sometimes called the e-fuels or synthetic fuel, and without going into too much chemistry, these are the more advanced fuels. In this process, natural gas is combined with air and then introduced into a chamber along with a catalyst, usually a compound containing cobalt or iron. TDI engines depend on injector pressures reaching about 1600 barr (espresso is made at 12-16 barr). With the clean-burning synthetic fuels, both gasoline and diesel can be operated in the usual manner, and the existing filling station network could be used accordingly. The widest-used form of synthetic fuel is liquefied coal and its derivatives. Once you change the lines, you should start with B20 for about four or five tanks to flush the petrodiesel sludge from your tank. Shale oil is a form of syncrude produced from the rock marlstone. TECO, Progress Energy, DTE, and Marriott have taken advantage. This converts the hydrocarbons in the material into a form that is more easily burned as fuel [source: U.S. Department of the Interior]. Extra-heavy oil is one of several sources of syncrude, a type of synthetic fuel that closely resembles crude oil. These types of fuels are often called Fischer-Tropsch liquids, after the process used to create them. (Dec. 20, 2010)http://ngm.nationalgeographic.com/2009/03/canadian-oil-sands/kunzig-text, Martin, F. Jeffrey and William L. Kubic. Alternative Fuels and Advanced Vehicles Data Center. As a result, there has been a major impetus for gas and oil companies to use them, as many do - for example Shell, Exxon, Statoil, Rentech, and Syntroleum. It will also require huge capital investments to take the concept from theory to execution. This is similar to the process of refining crude oil into fuels, but more expensive and complicated. "Clean Alternative Fuels: Fischer-Tropsch." However, there are serious environmental drawbacks. @ GiraffeEars- If you want to run your TDI on Biodiesel, you are in luck. By contrast, a natural fuel would be something like oil. The process combines CO2 captured from the atmosphere through their Direct Air Capture system with hydrogen to produce hydrocarbon fuels. What is involved, and what would a conversion cost? Coal is carbon-rich and hydrogen-poor, so The first, indirect coal liquefaction (ICL), uses the same Fischer-Tropsch process as gas-to-liquids fuels. By far, the three most prominent processes are Coal-To-Liquids (CTL), Gas-To-Liquids (GTL) and Biomass-To-Liquids (BTL). Why is it so hard to cut dependence on gasoline? On the face of it, the idea isn’t insane. If crude flows like water, then extra-heavy oil flows like honey. The widest-used form of synthetic fuel is liquefied coal and its derivatives. Solid waste like old tires can be used to make feedstock for synfuel production. "Baseline Technical and Economic Assessment of a Commercial Scale Fischer-Tropsch Liquids Facility." BTL fuels can be made from wood, crops, straw and grain. It contains many more impurities than conventional crude oil, including sulfur, nitrogen and heavy metals that must be removed before the bitumen can be used for fuel [source: U.S. Energy Information Administration]. Syncrude production, on the other hand, results in a synthesized crude oil that has to be further refined to be commercially sold, just like conventional crude oil. (Dec. 10, 2010)http://www.afdc.energy.gov/afdc/pdfs/epa_fischer.pdf, Van Bibber, Lawrence. Diesel fuels and other petroleum products are traditionally manufactured by refining of crude oil. Water, acid, sand and liquid carbon dioxide are injected under heavy pressure into a natural gas well in New Mexico. One of the best set-ups for your TDI is an Elsbett Single Tank system. The resulting synthetic fuel can be blended or used on its own as gasoline, diesel, or jet fuel. Subscribe to our newsletter and learn something new every day. passionate about stem cell research, regenerative medicine, and life extension therapies. It would produce as much carbon as it consumes. Coal-to-liquids fuels can be more environmentally friendly, because they burn cleaner than conventional gasoline or diesel. Feb. 19, 2008. The New York Times. Like GTL, coal-to-liquids (CTL) fuels are produced by isolating the hydrocarbons in existing fossil fuels and converting them to a form of synthetic fuel that can be used in existing vehicles' engines. You will need a system that can heat the oil to almost 300 degrees before it hits the injectors. Five tons (about 4.5 metric tons) of feedstock (or approximately 3 acres or 1.2 hectares of crops) equal 1 ton (0.9 metric tons) of manufactured BTL [source: U.S. Energy Information Administration]. November 2007. The Fischer-Tropsch process, developed by Nazi Germany and used by Sasol in South Africa today is one of the most used for converting coal, as well as biomass or natural gas, into synthetic fuels. BTL is not nearly as widespread as other forms of synfuels, which means companies would have to invest a lot of money to get BTL programs up and running. Despite the cost, BTL could be easier on the environment in the long run, since plants grown to produce the fuel could cancel out some of its CO2 emissions. At best, e-fuels will delivery an 85% reduction in vehicle CO2 by 2050. Alternative Fuels and Advanced Vehicles Data Center. But there are also disadvantages. Los Alamos National Laboratory. Synthetic fuel can already be added to fossil fuels. Speight, James G. "Synthetic Fuels Handbook." This is why it needs to be changed a couple of times. The most widely used method for converting gas to liquid fuels is the Fischer-Tropsch process (F-T synthesis) [source: U.S. Energy Information Administration]. Synfuels still remain more expensive to produce than conventional fuels, mostly because more research, development and investment are necessary to make production economically viable. "About Tar Sands." The chemical separation process creates a more pure fuel, because impurities can be filtered out easily. McGraw-Hill. (Dec. 10, 2010)http://www1.eere.energy.gov/biomass/thermochemical_processes.html, United States Department of the Interior, Bureau of Land Management. National Energy Technology Laboratory, U.S. Department of Energy. (Dec. 10, 2010)http://www.eia.doe.gov/oiaf/archive/aeo06/pdf/issues.pdf, United States Environmental Protection Agency. No need to hoard Carbon capturing will be a term you’ll here more of in the coming years. However, they can be also produced synthetically from various carbon bearing feedstocks. GTL, like other Fischer-Tropsch fuels, produces fewer emissions when burned [source: U.S. Environmental Protection Agency]. How hard is it to convert a vehicle to biodiesel fuels? But one option, synthetic fuels -- or synfuels -- offers some advantages and some drawbacks when compared to conventional oil-based fossil fuels. "Gas to Liquids." F-T synthesis can produce diesel fuels, naphtha (which can be processed to make gasoline) and industrial lubricants [source: U.S. Energy Information Administration].
