Title:
SILICALITE-1 MOLECULAR SIEVE-BASED CATALYST AND PREPARATION METHOD FOR 1,2-PENTANEDIOL USING SAID CATALYST
Document Type and Number:
WIPO Patent Application WO/2019/014969
Kind Code:
A1
Abstract:
An organic base functionalized silicalite-1 molecular sieve-encapsulated metal nanoparticle catalyst and a preparation method therefor, as well as a method for preparing 1,2-pentanediol from biomass-derived furfuryl alcohol by hydrogenolysis using said catalyst. When the catalyst is used in a reaction preparing 1,2-pentanediol from furfuryl alcohol by hydrogenolysis, the catalyst has high hydrogenolysis activity under relatively mild reaction conditions, significantly increasing the conversion rate of furfuryl alcohol and 1,2-pentanediol selectivity in the reaction, while also not generating obvious byproduct furfuryl alcohol polymers; the catalyst has good stability and long life, and may be recovered for reuse after the reaction is complete by means of a simple filter, greatly reducing reaction costs and separation difficulty.
