Acidic Methanol Stripping Process That Reduces Sulfur Content of Biodiesel From Waste Greases

Acidic Methanol Stripping Process That Reduces Sulfur Content of Biodiesel From Waste Greases

The present invention provides a method of producing fatty acid alkyl esters from a lipid, comprising steps of introducing a gas comprising vapor of an alcohol selected from methanol, ethanol, 1-propanol, iso-propanol and butanols, into the lipid in a form of bubbles to enable the bubbles to pass th...

description The present invention provides a method of producing fatty acid alkyl esters from a lipid, comprising steps of introducing a gas comprising vapor of an alcohol selected from methanol, ethanol, 1-propanol, iso-propanol and butanols, into the lipid in a form of bubbles to enable the bubbles to pass through the lipid and be discharged from the lipid. The product may then be subjected to a transesterification process catalyzed by a base catalyst. The present invention is robust with low quality feedstocks thus significantly reduce production cost for biodiesel.
