Influence of catalytic systems on process of model object hydrogenation

Abstract

Abstract On the basis of β-FeOOH, Fe(OA)3, Fe3O4 iron and spherical catalysts NiO/SiO2, Fe2O3/SiO2 derived from slag waste coals of heating electrical stations, the hydrogenation of model polycyclic hydrocarbon at presence of nanodimensioned catalysts antracene was studied. On the example of conversion of anthracene, it was shown that upon release of hydrogenation of the product yield and degradation of polycyclic hydrocarbons in the hydrogenation, the mentioned catalyst systems appeared to be in the following order: nanoparticles β-FeOOH, Fe(OA)3 and Fe3O4>spherical catalysts NiO/SiO2, Fe2O3/SiO2>commercial cobalt-molybdenum catalyst. The results showed that the catalysts studied are promising catalysts for the hydrogenation of polycyclic hydrocarbons and may be used for direct coal liquefaction.
