FIELD: petroleum processing catalysts.
SUBSTANCE: invention relates to catalysts for deep hydrofining of hydrocarbon feedstock, in particular diesel fractions, to remove sulfur compounds. Invention, in particular, provides catalyst for hydrodesulfurization of diesel fractions including active component selected from group VIII and VIB metal oxides dispersed on alumina carrier, which is, in particular, composed of aluminum oxides, 85-95%, and H form or cation-substituted form of zeolite ZSM-5, mordenite, zeolite BEA, or zeolite Y, 5-15%. Active component is selected from oxides of molybdenum and cobalt and/or nickel. Carrier preparation method comprises precipitation of aluminum hydroxide, incorporation of zeolite in H form or cation-substituted form in amount 5-15% (based on final product) and peptizing agent into aluminum hydroxide powder, extrusion of resulting mixture, drying, and calcination at 450-600°C. Preparation of catalyst includes impregnation of above-defined carrier with complex solution of group VIII and VI metal salts in air or nitrogen flow at temperature not higher than 200°C. Diesel fraction hydrodesulfurization process is also described.
EFFECT: enhanced purification of diesel fractions.
