Abstract

The invention discloses the heavy and ungraded residual oil process method. The method comprises the following steps: hydrotreating the fixed bed and suspended bed, deasphalting and catalytic cracking the dissolvent, and graded treatmenting the heavy and ungraded residual oil raw material. The method comprises many characteristics, as follow: sufficiently utilizing the fixed bed and suspended bed by hydrotreating the two or more than two kinds of feeds respectively, improving the productivity of light oil; through adjusting the proportion of deasphalted oil in the feed of fixed bed hydrotreating, residual oil hydrogenation unit of fixed bed handling more residual oil, effectively decreasing the coke deposit rate on the hydrogenation catalyst, and extending the durability of catalyst; with the said technique, producing the more light end product.

Description

technical field [0001] The invention relates to a method for processing inferior heavy and residual oil. More specifically, it involves a method of treating inferior heavy and residual oil by using a combined refining process. The combined refining process used includes fixed bed residual oil hydrogenation, suspended bed residual oil hydrogenation, catalytic cracking and solvent deasphalting processes . Background technique [0002] Generally speaking, residual oil is the heaviest part remaining from the atmospheric and vacuum distillation (primary processing) of crude oil, which contains a large amount of harmful impurities and non-ideal components such as metals, sulfur, nitrogen, colloids, asphaltene, etc., and is difficult to hydrotreat Big. At present, the processes for processing heavy hydrocarbon raw materials mainly include fixed bed, suspended bed, ebullating bed and moving bed. Among them, the fixed bed residue hydrogenation process has been industrialized earlie...
