Title:
CATALYTIC REFORMING CATALYST PREPARATION METHOD AND CATALYTIC REFORMING CATALYST
Document Type and Number:
WIPO Patent Application WO/2023/173811
Kind Code:
A1
Abstract:
The present application provides a catalytic reforming catalyst preparation method and a catalytic reforming catalyst. The catalytic reforming catalyst preparation method of the present application comprises the following steps: 1) adding a platinum group metal precursor to a system comprising a first silicon source and an aluminum source for mixing, and then adding a second silicon source, so as to obtain a silicon-aluminum precursor coated with platinum group metals, the first silicon source comprising a silane compound containing aminopropyl; and 2) performing steam assisted crystallization on the silicon-aluminum precursor coated with the platinum group metal, so as to obtain the catalytic reforming catalyst. The catalytic reforming catalyst prepared by the preparation method of the present application has excellent stability and smaller molecular sieve grain size, and has excellent aromatics selectivity, aromatics yield, and carbon deposition resistance when used in catalytic reforming reaction.
