Title:
DIMETHYL BENZYL ALCOHOL HYDROGENOLYSIS CATALYST, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/108336
Kind Code:
A1
Abstract:
The present application provides a dimethyl benzyl alcohol hydrogenolysis catalyst, and a preparation method therefor and a use thereof. Active components of the dimethyl benzyl alcohol hydrogenolysis catalyst comprise Pd, Ru, Cu, and Ni, Pd and Ru in the active components are highly dispersed on a surface layer of the catalyst, thereby facilitating inhibiting the occurrence of side reactions such as excessive hydrogenation, and dimethyl benzyl alcohol diffused into a catalyst pore channel can be subjected to hydrogenolysis reaction under the catalysis of Cu and Ni to generate cumene while further hydrogenation is difficult to occur to generate a by-product isopropyl cyclohexane; a support of the dimethyl benzyl alcohol hydrogenolysis catalyst is a composite support comprising ZnO, SiO2, and Al2O3, thereby facilitating obtaining an efficient hydrogenolysis catalyst which has active components highly dispersed and is reliable in strength and moderate in acidity; the dimethyl benzyl alcohol hydrogenolysis catalyst of the present application has the advantages of being high in active component dispersity, smooth in catalyst pore channel and the like, and has excellent activity and selectivity when being used for preparing cumene by means of dimethyl benzyl alcohol hydrogenolysis.
