     Reaction was studied in a current of gas and also, by rate of change of pressure, in a closed system.  On Fe-type catalysts, in contrast to the Co-type catalysts, the intermediate step in the synthesis is the formation of carbides.  The change in the activity of the catalyst Fe-Cu-ThO₂-K₂CO₃-kieselguhr at the different moments of the contact process of formation of hydrocarbons from CO₂ and H₂ was studied by simultaneous application of the dynamic and static methods; the reaction of this contact mass to H₂, CO, and CO₂ separately and to water gas with addition of CO was also investigated.
