Title:
NI-COATED AL2O3@AL2O3-SIO2 CATALYST, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/157685
Kind Code:
A1
Abstract:
A Ni-coated Al2O3@Al2O3-SiO2 catalyst. The specific surface area of the catalyst is 98 m2/g-245 m2/g, and the pore volume is 0.25 cm3/g-1.1 cm3/g. The mass ratio of a carrier Al2O3 to an active component Ni is Al2O3:Ni = 100:4-26. The mass ratio of the carrier Al2O3 to a coating layer Al2O3-SiO2 is 0.01-1. Ni particles exist on the surface of the carrier Al2O3 in an amorphous or highly dispersed state and have a grain size of less than or equal to 8 nm. A SiO2 layer is located among the Ni particles. The catalyst is easy to prepare and has good selectivity.
