Non-hydrogen Catalytic Dewaxing for Oil Production

Abstract

Waste plastics can be converted to diesel oil and lube base oil by thermal pyrolysis and dewaxing. ZEM-5, H-ZEM-5, Fe/H-ZEM-5 and Co/H-ZEM-5 catalyst were prepared. The influences of additive metals and type of molecular sieves on catalyst were discussed. The results showed that the additon of metallic components enhances the activity of catalyst, produces the low pour point diesel oil, and greatly reduces the pour point of lube base oil. The catalyst impregnated with Fe was more effective than one impregnated with Co. The qualities of oil production were also improved more with H-ZEM-5 than ZEM-5.
