Title:
CATALYST FOR ISOMERIZING FATTY ACID METHYL ESTER, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/045763
Kind Code:
A1
Abstract:
A catalyst for isomerizing a fatty acid methyl ester and a preparation method therefor. The catalyst comprises a noble metal Ru, TiO2, SiO2, and an SAPO-11 molecular sieve. Using the mass of the SAPO-11 molecular sieve as a benchmark, the content of Ru is 1-15% of the mass of the SAPO-11 molecular sieve, the content of SiO2 is 0.5-10% of the mass of the SAPO-11 molecular sieve, and the content of TiO2 is 0.5-10% of the mass of the SAPO-11 molecular sieve. The catalyst has high activity during an isomerization reaction of a fatty acid methyl ester, the conversion rate of the fatty acid methyl ester is more than 90%, the selectivity of the iso-fatty acid methyl ester is more than 95%, and the selectivity of isoparaffin is less than 5%.
