Title:
EXTRUSION MOLDING METHOD FOR COPPER-BASED ACETOPHENONE HYDROGENATION CATALYST AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/226114
Kind Code:
A1
Abstract:
The present invention provides an extrusion molding method for an acetophenone hydrogenation catalyst, comprising: kneading catalyst raw powder, a silica sol, deionized water, an extrusion aid, and a pore expanding agent into a plastomer in a certain proportion, and then extruding, drying, and roasting to prepare a strip-shaped catalyst. The pore channel structure of the catalyst can be obviously improved by adding the pore expanding agent, such that phenethyl alcohol generated by hydrogenation of acetophenone can be rapidly diffused out of the pore channel of the catalyst, the residence time of phenethyl alcohol on the surface of the catalyst is shortened, and the generation of a byproduct ethylbenzene is effectively reduced; and meanwhile, the heat released by catalytic hydrogenation can also be rapidly removed, such that the agglomeration of copper nanoparticles is effectively avoided, and the service life of the catalyst is prolonged.
