NON-SUPPORTED BIMETALLIC HYDROGENATION CATALYST, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

WIPO Patent Application WO/2023/071936

A1

A non-supported bimetallic hydrogenation catalyst, and a preparation method therefor and an application thereof. The catalyst is composed of a complex formed by bonding a metal central atom or central ion to an organic ligand by means of a coordinate bond. The catalyst has a schematic composition represented by general formula (I): M1M2Oa[R(COO)x]b(I), wherein M 1 and M2 represent metals, R(COO)x represents an organic ligand, R represents hydrocarbyl in the organic ligand, COO represents coordinating groups in the organic ligand, x represents the number of the coordinating groups in the organic ligand, a represents a molar ratio of a non-coordinately bonded oxygen atom linked to the metals to the total amount of the metals, and b represents a molar ratio of the organic ligand to the total amount of the metals. The catalyst and a composition thereof are high in oil-phase dispersibility, hydrogenation activity and target product selectivity when being used in a hydrogenation reaction of a hydrocarbon-containing raw material.
