Title:
CATALYST FOR PREPARING DIAMINE BY HYDROGENATION OF DINITRILE, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/089487
Kind Code:
A1
Abstract:
Disclosed in the present invention is a catalyst for preparing diamine by hydrogenation of dinitrile, comprising the following components or reaction products thereof: a) active components, which comprise Ni and/or oxides thereof; b) additives, which comprise one or more of Mg, Cu, Co, Zn, Zr, Mo and/or oxides thereof; and c) a carrier, wherein the relative content of α-NiO in the catalyst is lower than 2.0a.u.. Also disclosed in the present invention is a method for preparing diamine by hydrogenation of dinitrile. The catalyst and method in the present invention greatly reduce the generation of by-products of excessive hydrogenation, and improves the overall selectivity of a target product.
