The regularities of carbon dioxide hydrogenation on a Fe-containing catalyst supported on a carbon carrier was studied in the temperature range of 250—400 °C at a pressure of 0.1 and 8.5 MPa. During the CO₂ hydrogenation at 0.1 MPa, only CO is formed. At 8.5 MPa, a deeper hydrogenation of CO₂ occurs with hydrocarbons formation (the value of the chain growth probability coefficient α = 0.54—0.65), the selectivity to which increases with increasing temperature. The best results for hydrocarbon formation were obtained at 8.5 MPa and 400 °C, with the C₂—C₄ olefin-to-alkane ratio reaching 1.6.
