Acidic methanol stripping process that reduces sulfur content of biodiesel from waste greases |
摘要 |
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. |

1. A method of producing fatty acid alkyl esters from a lipid, comprising steps of:
introducing a gas comprising vapor containing an alcohol into the lipid in a bubble column reactor in a form of bubbles to enable the bubbles to pass through the lipid and be discharged from the lipid; and adding an alcohol solution of an acid catalyst to the lipid in the bubble column reactor. |
