Abstract	This paper is devoted to the cooperative works of the Institute of Hydrocarbon Processing (Siberian Branch, Russian Academy of Sciences) and JSC Gazprom Neft-Omsk Refinery on the creation of cracking catalysts and additives to them with the purpose of increasing the yield of C$_{3}$-C$_{4}$ olefins, reducing the concentration of sulfur compounds in the gasoline product, and ensuring the afterburning of CO during the regeneration of a catalyst. Bizeolite cracking catalysts, which give yields of C$_{3}$-C$_{4}$ olefins of no less than 30 wt % and allow us to vary the composition and yield of target reaction products within wide ranges, are developed. Mixed oxides or modified Y and/or ZSM-5 zeolites are proposed as cracking catalyst additives that result in a 35% reduction in the concentration of sulfur compounds in gasoline (as compared to an equilibrium catalyst). A manganese oxide based additive is proposed for the efficient afterburning of CO, and a pilot batch of this additive is produced by JSC Gazprom Neft-Omsk Refinery and tested at an industrial plant. It is shown that the amount of manganese oxide based additive required to ensure a residual CO concentration of less than 20 ppm is 20% lower than for a platinum-containing additive. The developed catalysts and additives to them can be synthesized on the basis of the catalysts produced at JSC Gazprom Neft-Omsk Refinery.
