How's it Made?

A fat or oil is reacted with an alcohol, like methanol, in the presence of a catalyst to produce glycerin and methyl esters or biodiesel. The methanol is charged in excess to assists in quick conversion and recovered for reuse. The catalyst is usually sodium or potassium hydroxide which has already been mixed with methanol.

Pristine BioDiesel Technology

The production of biodiesel, or alkyl esters, is well known. There are three basic routes to ester production from oils to fats:

• Base catalyzed transeterification of the oil with alcohol
• Direct acid catalyzed esterification of the oil with methanol
• Conversion of the oil to fatty acids, and then to Alkyl esters with Acid catalysis

Our process is detailed in the diagram below.
