Abstract

The possibility of hydroprocessing the plastic waste pyrolysis product to produce valuable hydrocarbons was investigated. Catalytic tests were conducted in a flow mode at T = 310°C, P_H2 = 80 bar, and LHSV = 1 h^–1 over a fixed bed of a macro–mesoporous CoMoNi/Al₂O₃ catalyst using a pyrolysis oil fraction (polyethylene–polypropylene mixture) with T_boil < 360°C as the feedstock. The hydroprocessing led to the formation of a product exhibiting the properties of kerosene, except for boiling point and cloud point. It was found that acidic additives (zeolite or zeolite-like materials) should be introduced into the catalyst for the implementation of isomerization and cracking processes.

塑料废弃物催化加氢制有价碳氢化合物的研究

探讨了塑料废弃物热解产物加氢生产有价烃类的可能性。在固定床上以大介孔CoMoNi/Al2O3催化剂为催化剂，在T = 310℃，PH2 = 80 bar, LHSV = 1 h-1的流动模式下进行了催化试验，催化剂采用热解油馏分（聚乙烯-聚丙烯混合物），Tboil <； 360℃为原料。加氢处理导致产物的形成，除了沸点和浊点不同外，表现出煤油的特性。研究发现，在催化剂中应加入酸性添加剂（沸石或类沸石材料）以实现异构化和裂化过程。
