HIGHLY ACTIVE AND HYDROTHERMALLY STABLE CATALYST AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2023/036154

A1

A highly active and hydrothermally stable catalyst and a preparation method therefor. The catalyst is prepared by mixing highly active and hydrothermally stable catalyst powder with a binder and a forming agent and forming a spherical or strip-shaped catalyst by means of a molding device, and then drying and roasting the spherical or strip-shaped catalyst, wherein the mass percentages of components of the highly active and hydrothermally stable catalyst powder are: 0.02-20wt% of a covering component, 0.02-10wt% of doping metal, 0.02-10wt% of rare earth metal, and 60-99.4wt% of precursor. The highly active and hydrothermally stable catalyst has a specific surface area of 200-390 m2/g after treatment under high-temperature hydrothermal conditions, has high activity and hydrothermal stability, and is applicable to catalytic reactions under high-temperature hydrothermal process conditions.
