Currently, there are many unclaimed or irrationally used carbon-containing resources in the Russian Federation (associated petroleum gases, coal mine methane, natural gas from low-yield deposits, etc.), processing which can produce products with high added value: long-chain hydrocarbons (ceresins), high-quality motor fuels, raw materials for petrochemicals (olefins, components of base oils, etc.). The effective use of these resources requires the development of new technologies that will allow them to be processed cost-effectively. One of the main factors contributing to a significant improvement in the economic performance of the process is an increase in productivity, selectivity and stability of the catalysts. Therefore, this project is aimed at solving the fundamental problem of controlling the selectivity of the synthesis of hydrocarbons from CO and H2 and creating on this basis highly efficient catalytic systems and methods for producing long-chain hydrocarbons, motor fuels, valuable substances for petrochemistry. Within the framework of this project, systematic studies have made it possible to establish new patterns of hydrocarbon synthesis at elevated pressure (up to 10 MPa), circulation of gas, liquid hydrocarbons and water on: a) monofunctional Co-Al2O3/SiO2 catalysts and b) multifunctional catalytic systems that combine the active components of the hydrocarbon synthesis catalyst (Co-Al2O3/SiO2), hydrogenating zeolite (ZSM-5, SAPO-11, BEA, MOR, HY) and hydrogenating (Pt, Pd, Ni) components. The implementation of the project made it possible to obtain the scientific basis for the creation of strategically important industrial multifunctional catalytic systems and technologies for the production of hydrocarbons of a given composition.
