Abstract: This disclosure relates to a procedure, which through the application of a catalyst in homogeneous phase, allows the transformation of heavy hydrocarbons (vacuum residue, atmospheric residue, heavy and extra-heavy crudes) into hydrocarbons of lower molecular weight, characterized because after its application, the hydrocarbons obtain greater API gravity, lower kinematic viscosity and different composition by hydrocarbon families (SARA) that increases the proportion of saturated and aromatic resins and asphalts. The sulphur and nitrogen content is also reduced, resulting in higher yields to high commercial value distillates and a lighter product as compared to the original crude.

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.
