Catalytic processing of distillate fractions of chark chemical tar
Abstract
A highly efficient catalyst is developed and synthesized for the processes of hydropurification and ennoblement of chark chemical tar by means of application Mo-humate of complex onto the surface of nickel skeleton. On 5% Mo-Hu/Ni-Re catalyst the yield of gasoil fraction increases to 33%. The change is observed of group composition of hydrocarbon composition of gasoil fraction. The group and individual hydrocarbon composition of distillate of chark chemical fractions are determined by direct distillation and hydrogenised on 5% Mo-Hu/Ni-Re, with temperature of boiling from 180°С to 320°С. In the composition of lowtemperature fraction in comparison to direct distillation the lowering is observed of paraffines with 77.2% and 1.8%, naphthene and olefin hydrocarbons from 0.2% to 0.1%, the increase of isoparaffines from 15.9% to 85.5%, the quantity of aromatic hydrocarbons from 6.2% to 11.4%. The possibility is shown for preparation of motor fuel meeting the ecological standards.References
