Abstract

The RE-containing Si-base semi-synthesized hydrocarbon converting catalyst features are that it is prepared with silicon sol binder containing RE salt 0.1-20 % (by REO), natural aluminum silicate clay and artificially synthesized molecular sieve. With RE activated silica, the catalyst of the present invention has high heavy oil cracking activity, high heavy metal contamination resistance, low content of olefin and S in catalytically cracked gasoline.

Description

technical field [0001] The invention belongs to hydrocarbon cracking catalysts, more specifically, a semi-synthesized hydrocarbon cracking catalyst containing rare earth silica sol. Background technique [0002] Petroleum is an irreplaceable transportation fuel, and petroleum resources are limited. Therefore, developing deep conversion of heavy oil and increasing light oil products will still be a major development strategy for the oil refining industry in the 21st century. The product yield, quality and economic indicators of the heavy oil deep conversion process are closely related to the catalyst performance. my country has done a lot of research and development on cracking catalysts for deep processing of heavy oil, among which silica sol semi-synthetic hydrocarbon cracking catalyst is prepared with silica sol as binder, natural aluminum silicate clay and synthetic molecular sieve Heavy hydrocarbon catalytic cracking catalyst. Since the silica sol has almost no catalyti...
