This process also uses lye as a catalyst in the whole process.

How do they make biodiesel. Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid estersIt is typically made by chemically reacting lipids such as animal fat soybean oil or some other vegetable oil with an alcohol producing a methyl ethyl or propyl ester by the process of transesterification. An easy to understand explanation of the chemistry involved and the processes used to go from vegetable oil to biodiesel. If nothing settles out then you have created highly converted fuel.

The process for making biodiesel uses an oil a catalyst and an alcohol. At the end of the process all the glycerin sinks down at the bottom and all the biofuel rests at the top. Unlike the vegetable and waste oils used to fuel converted diesel.

Please read up on this before you start and please understand. In this process the fat or oil is first purified and then reacted with an alcohol usually methanol CH3OH or ethanol CH3CH2OH in the presence of a catalyst such as potassium hydroxide KOH or sodium hydroxide NaOH. Waste vegi oil WVO NaOH lye and methanol.

Energy Self Sufficiency Newsletter. Allow the heavier glycerin to settle out for a few hours. Many students have heard of biodiesel without realizing that to produce the fuel from waste vegetable oil is a fairly simple process.

Measure 27 mL of methanol to the vial. Add exactly 3 mL of room temperature biodiesel into the vial. Some of the chemicals which are used in the manufacturing of biofuels.

They also praise the American industry mainly the automotive industry and its great engineering capability of developing special vehicles. In some cases these ILUC emissions are so high that some biofuels lead to higher GHG emissions than the fossil fuel they replace when taking into account the whole life-cycle emissions. An easy-to-follow step-by-step guide that will help you make Biodiesel.
