The features of hydrogenation of carbon monoxide and carbon dioxide over the Fe-based Fe/C and FeK/C catalysts were studied. The promotion of the iron-based catalyst on the carbon support with potassium at equal CO2 conversions leads to an increase in the chain growth probability (α) and in a significant increase in the selectivity to C5+ hydrocarbons, including olefins. Carbon dioxide hydrogenation was studied in a wide pressure range. Only CO is formed as a result of CO2 hydrogenation at a pressure of 0.1 MPa and temperatures from 300 to 400 S. An increase in pressure up to 2.0 MPa leads to a deeper hydrogenation of SO2 to saturated and unsaturated hydrocarbons with α = 0.54—0.66. A further pressure increase up to 6.5—8.5 MPa makes it possible to enhance the selectivity to hydrocarbons. A higher value of the chain growth probability (α = 0.78) was obtained over the FeK/C catalyst in the Fischer—Tropsch synthesis.
