Problems solved by technology

Among the disclosed technologies, CN02826756.7 is a method for transesterification of fat and / or oil through heterogeneous catalysis, and CN200410038292.4 is for preparing biodiesel through solid acid or alkali catalyzed transesterification of grease and methanol, without sewage discharge, which is harmful to the environment No pollution, but due to the poor compatibility between the reactant methanol and oil, and the difficulty of mass transfer in the multi-phase or single-phase solid acid or alkali during the reaction process, the reaction process takes a long time and consumes a lot of energy
CN200510012660.2 states that the production of biodiesel through solid alkali catalyzed oil transesterification solves the problem of mass transfer between phases, the reaction time is short, and there is no liquid acid-base catalyst pollution, but the molar ratio of oil to alcohol is high, methanol recovery pressure is high, energy consumption is high, and High requirements for equipment, large investment, and certain difficulties in industrialization

Abstract

The present invention provides one kind of catalyst system for producing biological diesel oil, and the catalyst system includes active acid catalytic composition and active alkaline catalytic composition. The present invention also provides biological diesel oil producing process with the catalyst system. The biological diesel oil producing process includes the steps of: the esterification of grease and/or acidified oil in the presence of acid catalytic composition and the subsequent ester exchange reaction in the presence of alkaline catalytic composition. The process converts grease and/or acidified oil into biological diesel oil completely. The present invention has the advantages of high catalytic activity of the catalyst system, short reaction period, low reaction temperature, high yield, low production cost, less corrosion to the production apparatus, high product quality, low power consumption, less pollution, etc.

Description

technical field [0001] The invention relates to the field of bio-renewable energy, in particular to a catalyst system for producing biodiesel and a method for producing biodiesel by using the catalyst system. Background technique [0002] Bioengineering is recognized as the "engineering of the century" and will promote the progress of the "fourth wave". By the middle of this century, its industrial scale will reach 10 times that of the information technology industry. Among them, bioenergy and biomaterials will replace petroleum and its products, occupying half of the consumer market. Developed countries in Europe and the United States regard the development of bio-energy and bio-materials as a "national strategy". Biodiesel (biodiesel) is clean and renewable energy. It uses oil crops such as soybeans and rapeseeds, oil-bearing forest fruits such as oil palm and pistachio, engineering microalgae and other oil-bearing aquatic plants, animal fats, waste cooking oil, acidified...
