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.

Abstract: An oily sewage pretreatment method without air flotation, comprising the following steps: (a) sedimentation separation: performing sedimentation separation on oily sewage to implement preliminary separation of oil, sludge, and water; (b) boiling bed separation: performing boiling bed separation on the oily sewage obtained by the preliminary separation to further remove dispersed oil, sludge, and sand from the oily sewage; (c) shape coalescence separation: performing shape coalescence separation on the oily sewage obtained by the boiling bed separation in step (b) to implement demulsification, coalescence, and separation of emulsified oil; and (d) biochemical treatment: the effluent obtained in step (c) directly enters an AOH biochemical system, an air flotation unit is omitted. Also disclosed is an oily sewage pretreatment apparatus without air flotation.
