Method for producing fuel oil from waste plastics

The invention discloses a method for producing fuel oil from waste plastics. The method comprises the following steps: mixing waste plastics and solvent oil, heating and melting, filtering insoluble substances, and then carrying out flash evaporation recovery on the solvent oil to obtain molten plastics; mixing the molten plastic with decompression wax oil to obtain blend oil; in a hydrogen atmosphere, the blend oil is subjected to hydrofining and hydrocracking reactions in sequence under the action of a catalyst to generate fuel oil, and naphtha, kerosene and diesel oil are obtained through a fractionation system. According to the pretreatment process disclosed by the invention, inorganic additives in the waste plastics are effectively removed, and pollution and blockage to subsequent devices are reduced; meanwhile, the generation yield of gas products in the waste plastic treatment process is reduced, and naphtha, kerosene and diesel oil products are produced to the maximum extent. 本发明公开了一种废塑料生产燃料油的方法。该方法包括
