Process combined oil refining and gasification

Abstract

A process of oil refining and gasification comprising the steps of, (1) petroleum hydrocarbon and coke transfer agent contacting and reacting in reactor, (2) separating produced reaction oil gas and residual coke transfer agent after reaction, (3) coke transfer agent contacting water vapor and oxygen-containing gas under gasification condition to produce formed gas, (4) returning the regenerated coke transfer agent back to reactor in step (1) for circulation use. The process by the invention can not only improve the quality of heavy petroleum hydrocarbon, but also provide cheap raw material gas for hydrogen production process or C1 chemistry.

Description

technical field

[0001] The invention relates to a process method combining oil refining and gasification. Background technique

[0002] The development trend of heavy and inferior crude oil in the world and the increasingly stringent environmental protection regulations have brought many new problems to the petroleum processing industry. For example, the content of harmful elements such as sulfur, nitrogen, nickel, and vanadium in raw oil is high, and hydrogenation pretreatment is required; the hydrogen-carbon ratio of raw oil is low, and in order to increase the yield of high-value products such as gasoline and diesel, it is necessary to Hydrotreating: The inferiority of raw materials will inevitably affect the properties of the product. In order to improve the quality of gasoline and diesel, hydrofining has to be carried out. Therefore, the hydrogenation process has become an essential secondary processing method, which plays a very important role in oil refining enterpri...
