Copyrolysis upgrading method for coal tar pitch and oil sludge and carbon black raw material

Abstract

The invention belongs to the technical field of energy products, and in particular relates to a coal tar pitch and oil sludge CO-pyrolysis upgrading method and a carbon black raw material, which comprise the following steps of S1, pre-degrading organic alkali, thickened oil ester, inorganic heavy metal ions and filler in the oil sludge by actinomycetes and bacillus; the bacillus is classified as bacillus aryabhattai, the preservation address is China center for type culture collection, the preservation number is CCTCCNO: M20232038, S2, CO-pyrolysis is carried out, namely, the sludge subjected to pre-degradation in the step S1 is CO-pyrolyzed with coal tar pitch under the conditions of oxygen-enriched fuel gas and carbon black tail gas CO 2 , and the derivative is obtained. The utilization rate of the oil resource of the waste oil sludge is 85-90% through pre-degradation, co-pyrolysis, fractionation or reactive distillation, and the rest 10-15% is used as filler carbon black.
