Abstract

The invention discloses a liquid phase hydrogen desulfurization-separation and coupling refining method for petroleum refining coarse oil. The method comprises the following steps: (1) mixing coarse oil and hydrogen and entering into a hydrogenation reactor, and carrying out hydrogen desulfurization under the effect of a hydrogen desulfurization refining catalyst, wherein the use level of the hydrogen desulfurization refining catalyst is 1.0-10% by mass of the coarse oil, the hydrogen desulfurization refining catalyst is a metal supported catalyst, and a carrier is a heavy oil catalytic cracking waste accelerant; and (2) carrying out gas-liquid separation on the reaction product, wherein a gas phase substance flow is continuously extracted and washed and neutralized by alkali liquor; a liquid phase substance flow is extracted to obtain the refined oil. The method disclosed by the invention can be used for treating high-sulfur and high-nitrogen petroleum refining coarse oil so as to carry out hydrogen desulfurization-separation and coupling refining on the coarse oil under a relatively mild temperature and pressure operating condition, so that the equipment investment and operating expenses are greatly lowered.

Description

technical field [0001] The invention relates to the technical field of refinement of petroleum refining crude oil products, in particular to a liquid-phase hydrogenation desulfurization reaction-separation coupling refining method of petroleum refining crude oil products. Background technique [0002] Due to the rapid development of my country's economy, the demand for light oil products continues to rise. In order to increase the yield of light oil, most refineries tap the potential of residual oil and develop heavy oil catalytic cracking technology. After catalytic cracking of heavy oil, the yield of light oil can reach 66%, which can be used not only as gasoline and diesel products, but also as a high-quality raw material for petrochemical (ethylene production). However, the light diesel oil obtained from heavy oil catalytic cracking contains a large amount of olefins and a considerable amount of sulfur, nitrogen, oxygen impurities, etc., and the product quality is poor,...
