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 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. There are several methods for carrying out this transesterification reaction including the common batch process, heterogeneous catalysts, [ 74 ] supercritical processes, ultrasonic ...
Both HVO diesel (green diesel) and biodiesel are made from the same vegetable oil feedstock. However the processing technologies and chemical makeup of the two fuels differ. The chemical reaction commonly used to produce biodiesel is known as transesterification. [2] The production of biodiesel also makes glycerol, but the production of HVO ...
The molecules in biodiesel are primarily FAME, usually obtained from vegetable oils by transesterification. They are used to produce detergents and biodiesel. [1] FAME are typically produced by an alkali-catalyzed reaction between fats and methanol in the presence of base such as sodium hydroxide, sodium methoxide [2] or potassium hydroxide ...
It is also used to convert fats (triglycerides) into biodiesel. This conversion was one of the first uses. Transesterified vegetable oil was used to power heavy-duty vehicles in South Africa before World War II. It was patented in the US in the 1950s by Colgate, though biolipid transesterification may have been discovered much earlier.
Vegetable oil is used for transportation in four different ways: Vegetable oil blends - Mixing vegetable oil with diesel lets users get some of the advantages of burning vegetable oil and is often done with no modification to the vehicle. [4] Biodiesel - Biodiesel can be produced from vegetable oil through the process of transesterification ...
The following table shows the vegetable oil yields of common energy crops associated with biodiesel production. Included is growing zone data, relevant to farmers and agricultural scientists. This is unrelated to ethanol production, which relies on starch, sugar and cellulose content instead of oil yields.
The IEA estimates that biodiesel production used 17% of global vegetable oil supplies in 2021. [ 26 ] Oils and fats reacted with 10 pounds of a short-chain alcohol (usually methanol) in the presence of a catalyst (usually sodium hydroxide [NaOH] can be hydrogenated to give a diesel substitute.
