Neste has estimated that the use of NExBTL diesel cuts greenhouse gas emissions by 40 to 90 percent in comparison to fossil based diesel. [8] Due to the chemistry of the process, the renewable diesel is pure alkane and contains no aromatics, oxygen (although oxygen would have promoted cleaner combustion [9]) or sulfur. [3] [dead link ]
Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial bio waste.
Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity.

The Marathon Martinez Renewable Fuels Facility is located in the San Francisco Bay Area in an unincorporated area known as Avon, East of Martinez, California. It refines biobased feedstocks such as animal fat, soybean oil and corn oil into renewable diesel. Previously owned by Tidewater Petroleum, Tosco, Valero Energy, Tesoro and Marathon ...
U.S. renewable diesel production capacity nearly quadrupled following the coronavirus pandemic from just 791 million gallons a year in 2021 to 3 billion gallons by 2023, as refiners sought ways to ...
Renewable diesel from vegetable oil is a growing substitute for petroleum. [14] California fleets used over 200 million US gallons (760,000 m 3 ) of renewable diesel in 2017. The California Air Resources Board predicts that over 2 billion US gallons (7,600,000 m 3 ) of fuel will be consumed in the state under its Low Carbon Fuel Standard ...
A renewable diesel boom could also have a profound impact on the agricultural sector by swelling demand for oilseeds like soybeans and canola that compete with other crops for finite planting area ...
All synthetic hydrocarbons are generally produced at temperatures of 200–300 °C, and at pressures of 20 to 50 bar. Catalysts are usually used to improve the efficiency of the reaction and create the desired type of hydrocarbon fuel. Such reactions are exothermic and use about 3 mol of hydrogen per mole of carbon dioxide involved.
