Title:
CATALYST FOR HYDROGENOLYSIS AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/109611
Kind Code:
A1
Abstract:
A catalyst for hydrogenolysis which, when calculating on the basis of mass percent, comprises: (a) 40-80% of a component A; (b) 0.5-10% of a component B; (c) 0.01-1% of a component C; (d) 0.1-5% of a component D; (e) 10-50% of a component E. The preparation method for the catalyst comprises the following steps: (1) adding drops of a sodium carbonate solution and a first metal salt solution into deionized water; (2) adding a second metal salt solution and component E; (3) filtering, shaping, and calcinating the solution, and forming a catalyst product. By adding a small amount of a second metal component containing elements such as zinc, magnesium, calcium, and barium to the main components of the catalyst, which are copper, nickel, and palladium, it is possible to effectively increase the dispersion effects of the copper, nickel, and palladium main components in the catalyst while increasing the reactivity and reaction stability of the catalyst.
