Abstract

The invention provides a resin catalyst for producing fatty acid methyl ester from high-acid-value oil. The preparation method is implemented in a way that: highly-crosslinked styrene cation exchange resin is used as the base, and a small amount of double-link monounsaturated fatty acid is introduced in polymerization to enhance the compatibility between the catalyst and fatty acid, thereby enhancing the catalytic effect of the fatty acid methyl ester; and after the polymerization finishes, sulfonation is carried out, and unstable Cl-, SO4<2->, pigments and other impurities are removed from the finished resin product by pretreatment at high temperature under high pressure. The resin catalyst provided by the invention has the advantages of low catalyst consumption, continuous reaction, short reaction time, good catalytic effect, long service life and the like, can be widely used in production, and has wide application prospects in the field of production of biodiesel from high-acid-value oil.

Description

technical field [0001] The invention relates to a catalyst for producing fatty acid methyl esters and a preparation method thereof, in particular to a resin catalyst for producing fatty acid methyl esters from high-acid value oils and a preparation method thereof. technical background [0002] As an environmentally friendly renewable green energy, biodiesel is of great significance to solve the two major problems of energy shortage and environmental pollution in the world today. The development of biodiesel has great potential in our country, and will play a very important role in our country's existing energy structure, ensuring oil security, and protecting the environment and ecology. [0003] At present, the main factor restricting the development of biodiesel is the cost of raw materials, accounting for 60% to 75% of the total cost. Using refined oil as raw material for biodiesel is not economically feasible and does not meet the current national conditions in China. Us...
