METHOD OF PRETREATMENT OF GLYCERINE CONTAINING WASTE GENERATING FROM BIO-DIESEL PREPARATION FOR USING CARBON SOURCE OF CULTURE MEDIUM OF MICROORGANISM IN PREPARATION OF BIO-ETHANOL

摘要

PURPOSE: A pretreatment of glycerine-containing waste is provided to use culture liquid carbon source of a bioethanol-producing strain. CONSTITUTION: A pretreatment of glycerine-containing waste for using culture liquid carbon source comprises: a step of heating the waste to remove methanol; a step of adding acid to convert MONG components to fatty acid; and a step of isolating fatty acid. The acid is hydrochloric acid or phosphoric acid. The pretreatment is batch type or serial type.
