Abstract

The invention discloses a cracking gasification catalytic composition, a preparation method thereof and a petroleum hydrocarbon cracking gasification method. In weight percentage, the catalytic composition comprises: 1% to 50% of mesoporous active materials, wherein, The anhydrous chemical expression of the active mesoporous material in terms of oxide weight is (0-0.2) Na 2 O·(40-85)Al 2 o 3 ·(10-55)SiO2 2 ·(0.5-10)P 2 o 5 ·(0.5-10)M x o y , wherein the metal M is selected from Mg, one or more of the periodic table IIB, IIIB, IVB, VIIB group elements, and lanthanide rare earth elements, y is the highest valence state when the metal M forms an oxide, and x and The value of y is such that the valences of M and O are balanced. It has better cracking activity and gasification conversion performance when applied in heavy oil catalytic cracking-gasification combined process, and can obtain higher yield of liquefied gas.

Description

technical field [0001] The invention relates to a cracking gasification catalytic composition and a preparation method thereof, and a petroleum hydrocarbon cracking gasification method using the cracking gasification catalytic composition. 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 coking process will produce a large amount of low-value-added petroleum coke, so petroleum resources have not been efficiently utilized. [0003] Part of the coke produced by the fluidized coking and flexible coking processes developed by Exxon in the United States is burned to...
