Resumo
Со(Ni)–PMo(W)/Al2O3 catalysts are prepared using Keggin heteropoly acids H3PMo(W)12O40 and cobalt (nickel) citrate. The physicochemical properties of the catalysts are studied via low-temperature nitrogen adsorption, X-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy. Their catalytic properties are determined in the hydrotreatment of a model raw material containing dibenzothiophene, naphthalene, and different amounts of quinoline (up to 1000 ppm of nitrogen), and in the hydrotreatment of a straight-run diesel fraction and vacuum gas oil. The composition of Со(Ni)–PMo(W)/Al2O3 catalysts plays an important role in the hydrotreatment of a complex hydrocarbon raw material. Ni–PW/Al2O3 catalyst is more resistant to organonitrogen inhibitors than Ni(Co)–PMo/Al2O3 samples with more reactive active sites. Ni–PW/Al2O3 catalyst provides the greatest depth of conversion for sulfur- and nitrogen-containing compounds and polycyclic aromatic hydrocarbons in the hydrotreatment of vacuum gas oil.
