摘要： A process of producing a mesoporous beta zeolite includes mixing a crystalline beta zeolite with one or more solvents, cetyltrimethylammonium bromide, and metal hydroxide to produce a solution, heating the solution at a temperature of from 50° C. to 150° C. to convert the crystalline beta zeolite to a non-crystalline material with reduced silica content relative to the crystalline beta zeolite, cooling the solution to a temperature of from 25° C. to 40° C., adjusting the pH of the solution to from 8 to 10 by adding an acid, and aging the solution at a temperature of from 50° C. to 150° C. for a time period sufficient to crystalize the non-crystalline material to produce beta zeolite particles.

摘要： A method of preparing a cracking catalyst includes converting one or more clay mineral compositions to metakaolin; synthesizing an intermediate ZSM-5 zeolite from the metakaolin, a silica source, and ZSM-5 zeolite seeds; and forming a cracking catalyst comprising a hierarchical mesoporous ZSM-5 zeolite through disintegration and recrystallization of the intermediate ZSM-5 zeolite. A cracking catalyst for steam enhanced catalytic cracking of hydrocarbons includes a hierarchical mesoporous ZSM-5 zeolite impregnated with manganese, zirconium, or manganese and zirconium, where the cracking catalyst has a mesopore volume of at least 0.30 cubic centimeters per gram (cm3/g). A process for upgrading crude oil through steam enhanced catalytic cracking includes contacting the crude oil with steam in the presence of a cracking catalyst, where the cracking catalyst comprises a hierarchical mesoporous ZSM-5 zeolite impregnated with manganese, zirconium, or both manganese and zirconium.

摘要： An integrated process and associated system for conversion of crude oil to value added petrochemicals. The process includes separating crude oil into light and heavy crude fractions and processing the heavy fraction in a solvent deasphalting unit and a delayed coker unit, and then providing the light fraction and selected effluents of the solvent deasphalting unit and the delayed coker unit to a hydrotreater. The process further includes separating the effluent of the hydrotreater to generate a C1 fraction passed to a methane cracker, a C2 fraction passed to an ethane steam cracker, a C3-C4 fraction passed to a dehydrogenation reactor, a hydrotreated light fraction passed to an aromatization unit, and a hydrotreated heavy fraction passed to a steam enhanced catalytic cracking unit. The process further includes separating effluents of the various unit operations into product streams including a BTX stream and a light olefin stream.
