Abstract: The present disclosure relates to a method and apparatus for prolonging a continuous operation period of a methanol-to-olefins water washing process. The method may perform micro cyclone treatment on methanol-to-olefins washing water. The method may also deliver the washing water subjected to micro cyclone treatment and oil removal to a fluidized bed separator for treatment. The method may also adjust the backwash flow to release the intercepted catalyst powder and empty the dirt holding capacity of a pore. The method may also perform three-phase separation on a gas-liquid-solid mixture subjected to backwash, returning the obtained filter media to a particle bed layer, and respectively discharging a backwashing liquid a backwashing gas which comprise a catalyst. The method may also switch the fluidized bed separator to a normal working state, completing the active regeneration of the particle bed layer, and continuing to operate.

Abstract: A method and apparatus for hydrocracking mineralized refuse pyrolysis oil. The method may use the following steps: (a) crushing and pyrolyzing mineralized refuse to obtain arene and alkane precursor biomass oil; (b) hydrogenating the arene and alkane precursor biomass oil obtained in step (a), and separating the obtained hydrocrackate to obtain arene and alkane; and (c) purifying, recovering and optimizing the arene and alkane obtained in step (b), and performing deep processing to produce naphtha, jet fuel, light diesel oil, and heavy diesel oil.
