A process for continuous production of biodiesel from vegetable oils or animal fats by transesterification with methanol or ethanol to give crude fatty acid alkyl esters, subsequent washing with water in a wash column to remove water-soluble impurities, subsequent drying by vaporization of the water content and subsequent removal of steryl glycosides by adsorption onto calcium bentonite, wherein the adsorption column(s) used is/are regenerated in a first step, for desorption of the steryl glycosides, by rinsing with a mixture consisting of fatty acid alkyl esters and methanol or ethanol, and in a subsequent second step, for removal of methanol residues, by rinsing with fatty acid alkyl esters or with gaseous nitrogen or carbon dioxide.

Process for production of biodiesel

When producing hydrocarbons from fatty acid esters contained in fats or fat oils, the fatty acid esters initially are split up by hydrolytic decomposition into a first stream containing crude alcohol and water and a second stream containing free fatty acids, and subsequently the free fatty acids of the second stream are hydrogenated with hydrogen to obtain saturated hydrocarbons.
