Abstract
A method for making alkyl esters, or methylester specifically, such as biodiesel, from an oil source is described. The method involves simultaneously reacting the free fatty acids and glycerides of the oil source with methanol, under pressure up to 500 psia, into fatty acid alkyl esters. The conversion is catalyzed by an acid at temperatures between about 80° C. to about 200° C.
