Biodiesel is registered with the Environmental Protection Agency as a pure fuel or as a fuel additive and is a legal fuel in commerce. It is typically produced through the reaction of a vegetable oil or animal fat with methanol in the presence of a catalyst to yield glycerin and biodiesel (chemically called methyl esters). It is an alternative fuel that can be used by itself or blended with petroleum diesel for use in diesel engines. Its use can result in substantial reduction of unburned hydrocarbons, carbon monoxide, and particulate matter. Provisions of the Energy Conservation Reauthorization Act of 1998 (ECRA, P.L. 105-388) amended the Energy Policy Act of 1992 (EPACT, P.L. 102-486) to allow that the use of biodiesel added to conventional diesel at blends of 20% and higher would produce credits to offset up to 50% each year of alternative fuel vehicle acquisition requirements. Farmers and processors anticipate that increased use of biodiesel will strengthen the market for soybean oil.
A renewable diesel fuel substitute that can be made by chemically combining a natural oil or fat with an alcohol. Many vegetable oils, animal fats, and recycled cooking greases can be transformed into biodiesel fuel. Biodiesel is a nontoxic, biodegradable fuel that has been proven to provide lower exhaust emissions even when used in a blend called B20, which consists of 20% biodiesel and 80% petroleum-based diesel fuel.
Biodiesel is a cleaner-burning diesel replacement fuel made from natural, renewable sources such as new and used vegetable oils and animal fats. Like petroleum diesel, biodiesel operates in compression-ignition engines. Blends of up to 20% biodiesel (mixed with petroleum diesel fuels) can be used in nearly all diesel equipment and are compatible with most storage and distribution equipment. These low level blends (20% and less) don't require any engine modifications and can provide the same payload capacity as diesel. Using biodiesel in a conventional diesel engine substantially reduces emissions
More often a 'homemade' mix of vegetable oil for use in older vehicles with conventional diesel engines.
a cleaner burning fuel that is renewable and can be substituted for diesel fuel
a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils, animal fats or used cooking oils, meeting the requirements of ASTM D 6751. B100 or any percentage blend with petroleum diesel may be used in compression ignition engines without engine modification.
An alternative fuel for use in diesel engines that is made from natural renewable sources such animal fats or vegetable oils and does not contain petroleum. It has similar properties to petroleum but releases fewer environmental pollutants in its emissions. Biodiesel can be used in diesel engines with little or no modifications, either as a diesel fuel substitute, or added to petroleum-based fuels to reduce their polluting effect. Examples include oils such as soybeans, rapeseed, sunflowers or animal tallow.
A biodegradable transportation fuel for use in diesel engines that is produced through transesterification of organically derived oils or fats. Biodiesel is used as a component of diesel fuel. In the future it may be used as a replacement for diesel.
A biofuel in which organically-derived oils (soybean or canola oils, animal fats, waste vegetable oils, or microalgae oils) are combined with alcohol and blended with conventional diesel fuel or used by itself (see also "Biomass power")
The mono alkyl esters of long chain fatty acids derived from renewable lipid feedstocks, such as vegetable oils and animal fats, for use in compression ignition (diesel) engines. Manufactured by transestrification of the organic feedstock by methanol.
Is the name of a clean burning alternative fuel, produced from domestic, renewable resources. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.
An alternative fuel that can be made from any fat or vegetable oil. It can be used in any diesel engine with few or no modificaitons. It does not contain petroleum and can be blended with diesel or used in its pure form.
A renewable fuel in which soy oil is blended with standard diesel fuel and other additives. Biodiesel does not contain ethanol, but research is underway to develop diesel blends with ethanol (See “E diesel†below).
Biodiesel is a type of biofuel made by combining animal fat or vegetable oil (such as soybean oil or recycled restaurant grease) with alcohol and can be directly substituted for diesel as a stand-alone fuel (called B100, for 100% biodiesel) or be used as an additive (called B20, for 20% bio-diesel). Biodiesel can be used in vehicles (newer cars, usually 1994 or later, are required for B100) and is beginning to be used in on-site electricity generation and heating applications.
A renewable, low polluting fuel for most diesel internal combustion and turbine engines, containing methyl or ethyl esters made from fresh or waste vegetable or animal oils (triglycerides).
an alternative fuel generally blended with petroleum diesel to create a cleaner-burning biodiesel blend. A typical US blend might be 20% biodiesel to 80% petroleum.
Biodegradable transportation fuel for use in diesel engines that is produced from biomass (organically derived fats or oils).
Any liquid biofuel suitable as a diesel fuel substitute or diesel fuel additive or extender. Biodiesel fuels are typically made from oils such as soybeans, rapeseed, or sunflowers, or from animal tallow. Biodiesel can also be made from hydrocarbons derived from agricultural products such as rice hulls.
A variety of ester-based oxygenated fuel, usually made from soybean oil or other vegetable oils or animal fats
A biodegradable transportation fuel for use in diesel engines that is produced through the transesterfication of organically derived oils or fats. It may be used either as a replacement for or as a component of diesel fuel.
Produced through a process in which organically derived oils are combined with alcohol (ethanol or methanol) in the presence of a catalyst to form ethyl or methyl ester. Biodiesel can be made from soybean or Canola oils, animal fats, waste vegetable oils, or microalgae oils.
A petroleum diesel fuel substitute that is manufactured from vegetable oils, animal fats, or recycled greases combined with alcohol (ethanol or methanol) in the transeterification process.
A renewable fuel synthesized from soy beans, other oil crops, or animal tallow which can substitute for petroleum diesel fuel.
An environmentally safe, low polluting fuel for most diesel internal combustion and turbine engines. Can be mixed with petroleum diesel fuel and stored anywhere petroleum is. Made from fresh or waste vegetable oils (triglycerides) that are a renewable energy source. Both commercially and privately made around the world. Relatively safe and easy to process when conscientiously approached. Benefits are substantially reduced engine emissions, even with as small a blend as 20% Biodiesel with 80%petroleum diesel.
Biodiesel refers to a diesel-equivalent, processed fuel derived from biological sources (such as vegetable oils), which can be used in unmodified diesel-engined vehicles. It is thus distinguished from the straight vegetable oils (SVO) or waste vegetable oils (WVO) used as fuels in some modified diesel vehicles.
