Annotation: The article studies the reaction of obtaining high molecular weight hydrocarbons from the synthesis gas and the physicochemical characteristics of the catalyst containing Co-Fe-Ni-ZrO2/YuKTs used in this process. The increase in selectivity in methane formation is due, on the one hand, to the acceleration of the hydrogenation reaction of CO at the methane formation centers due to the increase in synthesis temperature and the diffusion of CO and H2 at different rates through zeolite pores. All fractions of hydrocarbons synthesized in the presence of hybrid catalysts contain large amounts of products of secondary conversion (cracking, isomerization) - isoparaffins and olefins. The high content of isoparaffins is recorded for the composite catalyst - the iso / n parameter is 0.6, which indicates an increase in its activity relative to the catalysts absorbed in the hydro-improvement reactions.
