Title:
SPHERE-LIKE SUPER-MACROPOROUS MESOPOROUS MATERIAL AND POLYOLEFIN CATALYST CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2021/243936
Kind Code:
A1
Abstract:
Disclosed are a sphere-like super-macroporous mesoporous material, a polyolefin catalyst, and a preparation method therefor and an olefin polymerization process. A sphere-like super-macroporous material has a two-dimensional hexagonal ordered pore channel structure; a mesoporous material has an average pore size of 10 nm to 15 nm, a specific surface area of 300 m 2/g to 400 m 2/g, and an average particle size of 1 μm to 3 μm; based on the total mass of the mesoporous material, the mass content of water in the mesoporous material is < 1 ppm; and the mass content of oxygen in the mesoporous material is < 1 ppm. When a polyolefin catalyst prepared with the mesoporous material as a carrier is used for an olefin polymerization reaction, the catalyst has a high catalytic efficiency and a polyolefin product with a narrow molecular weight distribution and a good melt index can be obtained.
