NOVELTY - Producing biodiesel involves adding lipid, fatty alcohol and solid base to the reaction vessel and then performing transesterification reaction, where the solid base is mixture of zinc oxide-calcium hydroxide-potassium fluroide and methylcyclopentadienyl manganese tricarbonyl, the lipid mass is 1-4 wt.%, and the mole ratio of fatty alcohol and lipid is 8-15:1. The obtained material is heated on water bath at 50-80 degrees C and at 2-6 megapascal and then the heated material is distilled to separate glycerol. The separated material is added with nonionic surface active agent.    USE - Method for producing biodiesel (claimed).    ADVANTAGE - The method enables to produce biodiesel in simple and cost-effective manner, and with high purity, high yield, high concentration of by-product glycerol and good raw material adaptability.    DETAILED DESCRIPTION - Producing biodiesel involves adding lipid, fatty alcohol and solid base to the reaction vessel and then performing transesterification reaction, where the solid base is mixture of zinc oxide-calcium hydroxide-potassium fluroide and methylcyclopentadienyl manganese tricarbonyl, the lipid mass is 1-4 wt.%, and the mole ratio of fatty alcohol and lipid is 8-15:1. The obtained material is heated on water bath at 50-80 degrees C and at 2-6 megapascal and then the heated material is distilled to separate glycerol. The separated material is added with nonionic surface active agent. The obtained material is filtered and then the filtered material is separated through ceramic film to separate mono-fatty acid ester and to obtain a high purity biological diesel oil. The hydrophilic lipophilic balance value of the non-ionic surface active agent is 3-25 and non-ionic surface active agent dosage of mixture mass is 0.1-10 wt.%. The support material is a ceramic film of the ceramic and film layer material is inorganic film. The inorganic film is selected from aluminum oxide or titanium oxide. The ceramic film aperture is 0.02-1.4 microns. The film separating operation is performed at 10-120 degrees C and at 0.08-0.5 megapascal pressure.
