Pure biodiesel (B-100) made from soybeans. Biodiesel is commonly produced by the transesterification of the vegetable oil or animal fat feedstock, and other non-edible raw materials such as frying oil, etc.
Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products .
Biodiesel B20 pump in Arlington, Virginia.. Biodiesel is commercially available in most oilseed-producing states in the United States.As of 2023, it is less expensive than petroleum-diesel, [1] though it is still commonly produced in relatively small quantities (in comparison to petroleum products and ethanol fuel).
Although these fuels were not better replacements, in 2008 the rise in fuel prices coupled with concerns about remaining petroleum reserves, led to the more widespread use of vegetable oil and biodiesel. The primary fuel used in Diesel engines is the eponymous diesel fuel, derived from the refinement of crude oil.
The energy content in the global production of bioethanol and biodiesel is 2.2 and 1.8 EJ per year, respectively. [17] Bioethanol is an alcohol made by fermentation, mostly from carbohydrates produced in sugar or starch crops such as maize, sugarcane, or sweet sorghum.
The United States produces mainly biodiesel and ethanol fuel, which uses corn as the main feedstock.The US is the world's largest producer of ethanol, having produced nearly 16 billion gallons in 2017 alone. [1]
Biodiesel currently has 3% of the diesel market in Germany and is the number 1 alternative fuel. [17] The German government has a Biofuels Roadmap in which they expect to reach 10% biofuels by 2010 with the diesel 10% coming from fuel made from vegetable oil.
In 2010, the United States imported about 4.3 billion barrels (680,000,000 m 3) of crude oil.Add to this about 2.01 billion barrels (320,000,000 m 3) produced in the United States, and the total consumption in the United States is 6.3 billion barrels (1.00 × 10 9 m 3) of crude for 2010.
