Abstract
This invention relates to the field of chemical catalysis and high-value utilization of waste oil resources, specifically to a supported molecular sieve catalyst, its preparation method and application, and a method for preparing methyl linoleate. The supported molecular sieve catalyst uses a molecular sieve as a support and a metal oxide as the active component; wherein the active component is selected from one or more of the following: molybdenum oxide, zirconium oxide, tungsten oxide, niobium oxide, zinc oxide, and aluminum oxide; the content of the active component in the supported molecular sieve catalyst is 0.1~50 wt%. This supported molecular sieve catalyst can achieve high catalytic activity and high product selectivity in linoleate esterification, and is highly stable, reusable, environmentally friendly, and can effectively replace traditional liquid acid catalysts.
