Hydrogenation treatment process for crude oil and crude oil reformed thereby

Abstract

There are disclosed a process for hydrogenating treating crude oil in the presence of a catalyst which comprises subjecting crude oil to consecutive hydrogenation demetalling treatment, hydrocracking treatment and hydrodesulfurization treatment to carry out hydrogenation treatment, subsequently carrying out gas-liquid separation in a gas-liquid separation step, and hydroreforming the resultant gas-phase fluid; and reformed crude oil or reformed topped crude oil which is produced by mixing the liquid-phase fluid produced from the gas-liquid separation step and the hydroreformed gas-phase fluid. The process markedly improves the qualities of kerosene and gas oil fractions in the product oil, which are expected to clear the prospectively intensified worldwide regulations on sulfur contents, aromatic components and the like.
