Abstract. Comparative laboratory tests were carried out on a new package of catalysts for the hydrotreating of gasoline fractions produced by LLC RN-kat, consisting of catalysts RN-2152 (nickel-molybdenum) (RN-2152 (NM)) and RN-2151 (cobalt-molybdenum) (RN-2151 (CM)). As comparison samples, catalysts for hydrotreating oil fractions AGKD-400 produced by JSC Angarsk Plant of Catalysts and Organic Synthesis (JSC APC and OS) were tested, in a package consisting of nickel-molybdenum and cobalt-molybdenum samples, as well as regenerated and passivated catalysts TK-578, passed two cycles of operation at a diesel fuel hydrotreating plant. Because of the analysis of the physicochemical characteristics of the catalysts, a reduced content of active components was noted in RN-2152 (NM) and RN-2151 (CM), along with high mechanical strength and developed specific surface area of these samples. The results of determining the total conversion of organosulfur and nitrogen components showed that the most active in terms of the set of hydrotreating reactions are the package of catalysts RN-2152 (AN), RN-2151 (CM). Industrial loading of the new package of catalysts was carried out at the hydrotreating unit for gasoline fractions of the Bashneft-Ufimsky Refinery, a branch of PJSC ANK Bashneft. The parameters of the initial activity of the catalysts under production conditions confirm the prediction of activity obtained as a result of laboratory tests.
