Abstract
A process for upgrading crude oil through steam enhanced catalytic cracking includes contacting crude oil with steam and a cracking catalyst at a mass ratio of steam to crude oil of 0.2-1. The cracking catalyst is a hierarchical mesoporous ZSM-5 zeolite impregnated with phosphorous, cerium, lanthanum, and iron. Contacting the crude oil with steam and the cracking catalyst cracks a portion of the crude oil to produce light olefins, light aromatic compounds, or both. The cracking catalyst is prepared by partially disintegrating a starting ZSM-5 zeolite in a first mixture comprising sodium hydroxide and a surfactant and, after the disintegrating, recrystallizing zeolite constituents in the presence of the surfactant to produce a recrystallized ZSM-5 zeolite having a hierarchical pore structure. The recrystallized ZSM-5 zeolite is recovered and calcined to produce the hierarchical mesoporous ZSM-5 zeolite, which is then impregnated with the phosphorous, lanthanum, cerium, and iron.
