Title:

SOLID BASE CATALYST AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2023/036155

Kind Code:

A1

Abstract:

Disclosed are a solid base catalyst and a preparation method therefor. The solid base catalyst is composed of an active component, an auxiliary agent, a forming aid and a solid base catalyst carrier. The solid base catalyst carrier is a highly mesoporous catalytic carrier. The solid base catalyst carrier has undergone a pore thickening treatment, transition metal doping, and a surface modification treatment, which improves the hydrothermal stability of the catalyst, eliminates some polar centers, reduces the ability of the catalyst to adsorb polycyclic aromatic hydrocarbons and non-hydrocarbon impurities in heavy oil, and increases the service life of the catalyst. The present invention further provides a preparation method for the solid base catalyst, which prepares microspherical, strip-shaped and spherical catalysts, and may be used in the reaction processes of fluidized bed catalytic cracking, fixed beds, moving beds and the like. The solid base catalyst of the present invention has a coke yield of less than 10 wt% and a selectivity of low-carbon olefins in liquefied gas greater than 80% during the catalytic cracking process of heavy oil and residual oil having a residual carbon content greater than 10 wt%.
