Multifunctional catalysis composition

Abstract

A multifunctional catalysis composition comprises 1-50wt% of a mesoporous aluminosilicate material, 1-40wt% of a gasification active component, 1-60wt% of a cracking active component, 0-70wt% of clay and 5-97wt% of a heatproof inorganic oxide matrix, wherein the mesoporous aluminosilicate material has a phase structure of pseudo-boehmite, has an anhydrous chemical expression formula of (0-0.3)Na2O.(40-90)Al2O3.(10-60)SiO2 by weight of oxide, and has a specific surface area of 200-400m<2> / g, a pore volume of 0.5-2.0mL / g, an average aperture of 8-20nm and a most probable aperture of 5-15nm The catalysis composition can reduce the gasification temperature of the cracking gasification conversion of hydrocarbon oil.

Description

technical field

[0001] The present invention relates to a kind of catalytic composition that is used in petroleum hydrocarbon cracking process and coke gasification combined process produced by cracking, more specifically, relates to a kind of processing and processing petroleum hydrocarbon raw material to produce light Fuel, and a multifunctional catalytic composition for the process of gasifying coke produced in the processing process into hydrogen or syngas with the participation of a gasification agent. Background technique

[0002] At present, when catalytic cracking processes heavy and low-quality feedstock oil, it poses challenges to the catalytic cracking process itself and the catalyst. Non-catalytic processing of low-quality heavy oil, including delayed coking, fluidized coking, and flexible coking, has attracted increasing attention. However, the coking process has the problems of high coke yield and low-quality coke that is difficult to utilize. The delayed cokin...
