Catalytic hydroprocessing of plastic waste into valuable hydrocarbons

The possibility of hydroprocessing of plastic waste pyrolysis product to obtain valuable hydrocarbons has been investigated. The catalytic experiment was carried out in the flow regime at T = 310 °C, P_H2 = 80 bar, LHSV = 0.5 h^-1 on a fixed bed of CoMoNi/Al₂O₃ catalyst, a fraction of pyrolysis oil (a mixture of polyethylene and polypropylene) with T_boiling < 360 °C was used as feedstock. As a result of processing, a product with the properties of kerosene, except for boiling point and turbidity, was obtained. The necessity of including acid additives (zeolite or zeolite-like materials) in the catalyst for isomerization and cracking processes was determined.
