NEW TYPE OF RANEY COPPER CATALYST AND METHOD FOR PREPARATION THEREOF AND APPLICATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/099489

Kind Code:

A1

Abstract:

Provided are a new type of Raney copper catalyst and method for preparation thereof and application thereof. The new type of Raney copper catalyst comprises aluminum, copper, and metal additive, said metal additive comprising one or a combination of Ni, Fe, Mo, Co, Ag, Pd, Pt, Au, and other elements. The preparation method comprises: high-temperature melting of a mixture containing copper/aluminum alloy and metal additive to obtain a mixed metal cured product, then crushing to obtain a catalyst precursor, then performing activation treatment to obtain a new type of Raney copper catalyst. The new type of Raney copper catalyst, on the basis of the synergistic effect between copper metal and different additive metals, exhibits good hydrogenation reaction capability. In comparison with Raney copper catalysts not having added metal additives, the present catalyst, when used in aqueous hydrogenation reaction of 3-hydroxypropionaldehyde to prepare 1,3-propanediol, has higher activity, better selectivity, and better stability, and the catalyst has relatively large particles which are easy to separate from the reactants.
