The reduction of carbon dioxide with molecular hydrogen in the presence of Fe,Cr-containing catalysts supported on a Sibunit carbon material at 400°C and pressures of 0.1 and 8.5 MPa is studied. Carbon monoxide can selectively form over the catalysts with an Fe : Cr ratio of 1 : 5. C1–C4 hydrocarbons with a predominance of methane are produced together with CO upon a decrease in the content of chromium (5Fe–0.25Cr/C sample). Transmission electron microscopy shows that the 5Fe–5Cr/C catalyst contains iron chromite FeCr2O4 (spinel structural type) as the main phase preventing the reduction of iron and the formation of iron carbides, which, in turn, provide the formation of hydrocarbons in the reaction of CO2 and H2.
