Abstract—The reduction of Fe2O3/SiO2 catalysts in flowing CO and CO + H2 in the temperature-programmed
and isothermal modes has been investigated by in situ magnetization measurements. The process takes place in
two steps, successively yielding magnetite and Hägg carbide. The carbide concentration in the case of reduction
with CO is higher than in the case of reduction with the CO + H2. This is assumed to be due to the formation
of Fe2SiO4 in the reduction of the catalysts with CO + H2.
Keywords: reduction, magnetization, catalyst, magnetite, Hägg carbide
