METHOD FOR ENZYME RECOVERY IN BIOFUEL PRODUCTION PROCESS

摘要

The invention relates to a method for enzyme recovery in biofuel production process. The method comprises steps of producing, by using liquid enzymes, an intermediate product mixture comprising a top phase comprising fatty acid esters and a bottom phase comprising glycerol; adding cationic polymer and an anionic surfactant or non-ionic surfactant to the intermediate product mixture; allowing an emulsion phase to form, the emulsion phase comprising liquid enzymes; and separating the emulsion phase from the intermediate product mixture.
