The study of the catalytic reforming process of light resin of pyrolysis
Sh.D. Aliyeva - Institute for Catalysis and Inorganic ChemistryThe conditions enabling to obtain benzene and toluene by catalytic processing of light resin are studied. Such resin is an environmentally hazardous waste of hydrocarbon production. The process of catalytic reforming of pyrolysis light resin was studied under laboratory conditions. The use of an aluminum complex catalyst in the process of pyrolysis of light resin allows reducing the temperature and pressure in the system. At the same time, the mass fraction of valuable aromatic hydrocarbons (benzene, toluene and other substances) increases in the system. The distillation residue of light resin can be used in the preparation of paints and varnishes, and as an insulator in electrical lines. Thus, the use of an aluminum-containing catalytic complex enables to accelerate the production of benzene and toluene. In this case, other valuable products are also obtained due to the pyrolysis of difficult-to-recycle, environmentally hazardous liquid waste.
