Abstract

The invention relates to bioengineering and energy sphere, specifically to a method for preparation of biogenic diesel using grease stores, in which the steps are as follows: a. evenly mixing low-carbon ester and fall according to a mole ratio of 3:1-1 2:1, and driving them with pump into reactor which can autocontrol the temperature; b. adding culture solution of vital cells which are extensively cultured and 10-30 % of grease quality, keeping the culture temperature of the vital cells and the catalyzed reaction temperature between 20 DEG C and 60 DEG C, after 5-60 hours, producing biogenic diesel and glyceryl triformate (glyceryl triacetate) by-product; c. separating cell, biogenic diesel and glyceryl triformate (glyceryl triacetate) by-product with centrifugal process and filtration method; d. making glyceryl triformate (glyceryl triacetate) by-product react with carbinol to produce low-carbon ester for recycle; e. preparing biogenic diesel which can meet a criterion by short-range distillation and rectification of the crude product of biogenic diesel obtained by filtration. The method can make production costs of industry of the biogenic diesel less than production costs of chemical method.

Description

Technical field: [0001] The invention relates to the fields of bioengineering and energy, in particular to a method for producing biodiesel through transesterification reaction of lipid-containing raw materials and low-carbon esters catalyzed by cultivating biological living cells. Background technique: [0002] At present, the production methods of biodiesel are mostly chemical and biological. The core of biodiesel production is the transesterification reaction of grease and some low-carbon alcohols (methanol or ethanol) under the action of a catalyst to generate the corresponding fatty acid methyl or ethyl ester. Chemical methods use acids and bases as catalysts. The biological method uses biological enzymes as catalysts. Chemical preparation of biodiesel uses excess alcohol to react with oil under certain temperature, pressure, and acid (or base) catalysis. After the reaction, it needs to be washed with water, neutralized, and distilled to recover excess alcohol and by-...
