Method for utilizing FCC slurry and coal to co-refine oil

The invention discloses a method for utilizing FCC slurry and coal to co-refine oil. The invention aims to solve the technical problems by providing the method, which is used for co-refining coal and oil by utilizing the FCC slurry and the coal as raw materials, and has high coal concentration and high conversion rates. The method adopts the technical scheme comprising the following steps of smashing and drying raw coal; mixing the dried pulverized coal, slurry oil, a catalyst, a cocatalyst and an additive to prepare oil and coal slurry; carrying out hydrogen cracking reaction through a suspended-bed reactor; separating to obtain heavy components and light components; mixing the heavy components with light components extracted through reduced pressure distillation and the separated light components; carrying out hydrorefining through a hydrorefining reactor; multistage distillation cutting a hydrorefined product into naphtha, diesel and other components. The technology is cross-cutting, meanwhile, the difficult problems of two industries of coal and oil refining are solved, and a platform for organic combination of cleaning coal efficient utilization and inferior FCC oil slurry deep processing is established.
