HYDROGENATION CATALYSTS AND METHOD FOR BENZOIC ACID HYDROGENATION REACTION
Document Type and Number:
WIPO Patent Application WO/2022/127550
Kind Code:
A1
Abstract:
Disclosed are hydrogenation catalysts and a method for benzoic acid hydrogenation reaction. The hydrogenation catalysts comprise a carrier, and an active component, auxiliary component and alkali metal element that are loaded on the carrier. The active component is ruthenium. The auxiliary component is one or more of nickel, iron and cobalt. The method for the hydrogenation reaction comprises a first hydrogenation step and a second hydrogenation step. A first hydrogenation catalyst and a second hydrogenation catalyst are the hydrogenation catalysts. The hydrogenation catalysts according to the present invention have high catalytic activity at a low temperature, and can react under relatively mild reaction conditions. The hydrogenation reaction method according to the present invention can implement the continuous and stable operation of a device, and meets industrial-scale operation requirements.
