Abstract

The effect the nature of a carbon material characterized by activated charcoal and sibunit has on the chemical composition and dynamics of activation of Fe-containing catalysts in CO and syngas atmospheres is investigated. It is established that magnetite with Т_θ = 572°С forms during the activation of Fe/С_act and FeCu/С_act in a CO flow; cementite with Т_θ = 220°С forms during the activation of Fe/С_Sib and FeCu/С_Sib in a CO flow; and activation in a СО/Н₂ flow results in the formation of Hägg carbide χ-Fe₅С₂ with Т_θ = 257°С with all catalysts.
