The main technologies of CO2 capture are based on the processes of absorption-desorption in absorbing solutions, membrane separation, adsorption, mineralization, etc. The main goal of the work was to develop a promising method of CO2 utilization by hydrogenation of iron carbonate, which is formed by absorbing carbon dioxide from industrial emissions by iron-containing nanoparticles capable of adsorbing up to 80% of CO2 by mass, forming a material similar to natural siderite (FeCO3). The obtained sample of synthetic siderite is an X-ray amorphous fine mixture of iron carbonate and hematite with impurities of goethite and wustite. It is shown that low-temperature hydrogenation of iron carbonate at a temperature of 250 ° С and a pressure of 6 MPa allows to obtain higher fuel hydrocarbons. At the same time the problem with utilization of the fulfilled sorbent by its regeneration is solved. Thus, converting CO2 from harmful greenhouse gas into valuable value-added products will not only mitigate the negative effects of CO2 emissions, but also provide valuable fuels, which in turn will increase energy security in light of fossil depletion.
