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. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.
The US National Renewable Energy Laboratory (NREL) states that energy security is the number one driving force behind the US biofuels programme, [114] and a White House "Energy Security for the 21st Century" paper makes it clear that energy security is a major reason for promoting biodiesel. [115]
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 ...
Consumption and Production of biofuels has played an essential role in the gasoline economy since the beginning of the 1980s. [3] Most recently, companies and organizations, such as the federal Renewable Fuel Standard (RFS) Program and California's Low Carbon Fuel Storage have set initiatives to promote the use of biofuels and reduce fossil ...
Microalgae-biofuel production costs a larger amount of money compared to fossil fuel production. The cost estimation of producing microalgae-biofuel is around $3.1 per litre ($11.57/US gal), [55] which is considerably more expensive than conventional gasoline. However, when compared with electrification of the vehicle fleet – a key advantage ...
Agricultural chemistry encompases the science and technology of producing not only edible crops, but feedstocks for fuels ("biofuels") and materials. Ethanol fuel obtained by fermentation of sugars. Biodiesel is derived from fats, both animal- and plant-derived. Methane can be recovered from manure and other ag wastes by microbial action.
Hydrotreated vegetable oil (HVO) is a biofuel made by the hydrocracking or hydrogenation of vegetable oil. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation adds hydrogen to molecules. These methods can be used to create substitutes for gasoline, diesel, propane, kerosene and other chemical feedstock.
