Title:
PSEUDO-BOEHMITE AND PREPARATION METHOD THEREFOR, AND CATALYTIC CRACKING CATALYST COMPRISING PSEUDO-BOEHMITE AND PREPARATION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/232021
Kind Code:
A1
Abstract:
Provided in the present invention is a pseudo-boehmite. The ratio of a grain size D(130) to a grain size D(020) of the pseudo-boehmite is D(130)/D(020) = 1.0-1.5, preferably, 1.1-1.3. Further provided in the present invention are a preparation method for the pseudo-boehmite, a catalytic cracking catalyst comprising the pseudo-boehmite, and a preparation method for and the use of the catalytic cracking catalyst. The pseudo-boehmite is used in a catalytic cracking catalyst, wherein an obvious mesopore distribution can be generated under the condition that the strength of the catalyst is up to standard, such that the pore structure of the catalyst is significantly improved, which has important significance in terms of promoting the efficient diffusion of a heavy oil macromolecule, a reaction intermediate and a product molecule in the catalyst, reducing the coke yield and optimizing the product distribution. The preparation method for the pseudo-boehmite is green and environmentally friendly, is low in terms of cost, and is easy to implement.
