The authors gave the relationship for the calculation of biodiesel yield as follows.

How is biodiesel made transesterification. The main purpose of transesterification is to reduce the viscosity and to increase the volatility of the vegetable oil. Transesterification is a chemical reaction used for the conversion of triglycerides fats contained in oils Feedstocks into usable biodiesel. The biodiesel separated after acidic transesterification reaction was washed with petroleum ether and then with hot distilled water 50 C until the washing reached a neutral pH.

Essentially the process thins down the oil to allow it to run in an unmodified diesel engine. Click to see full answer. The process leaves behind two products methyl esters and glycerin.

Biodiesel produced by the process of transesterification has a much lower viscosity making it capable of replacing petroleum diesel in diesel engines. Most biodiesel is made from soybean oil or used cooking oil from the restaurant industry but it can be made from most any renewable plant or animal fat. Biodiesel Recipes The method shown above is just the basic information of how Biodiesel can be made.

Most contemporary biodiesel is produced from waste vegetable oil sourced from restaurants chip shops and industrial food producers. The biodiesel production method applied worldwide at. Transesterification for Biodiesel Conversion.

Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. Biodiesel production is generally accomplished by the transesterification of vegetable oils and animal fats with a short chain alcohol mostly methanol in the presence of an alkali catalyst. The process of converting vegetable oil into biodiesel fuel is called transesterification or neutralizing the free fatty acids in oil removing the glycerol and creating an alcohol ester.

It is typically made by chemically reacting lipids such as animal fat tallow soybean oil or some other vegetable oil with an alcohol producing a methyl ethyl or propyl ester by the process of transesterification. This is accomplished by mixing methanol with sodium hydroxide or potassium Hydroxide to make sodium or potassium methoxide. Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters.
