Abstract

A multifunctional catalysis composition comprises 1-70wt% of a mesoporous aluminosilicate material, 1-60wt% of a gasification active component, 0-70wt% of clay and 5-98wt% of a heatproof inorganic oxide by oxide, 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 is used for the cracking gasification of heavy petroleum hydrocarbons, and realizes a low gasification temperature.

Description

technical field [0001] The present invention relates to a catalytic composition used in the cracking process of heavy petroleum hydrocarbons and the coke gasification combined process produced by cracking, more specifically, relates to a method for processing heavy petroleum hydrocarbons by using thermal cracking or / and catalytic cracking processes It is a multifunctional catalytic composition for the process of producing light fuel from raw materials and gasifying the coke produced in the process into hydrogen or synthesis gas with the participation of 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 a...
