Influence of Structural Properties of Support on the Activation of Fe–K/MgAl2O4 Catalysts in Syngas

Аннотация

The influence of the structural properties of the aluminum magnesium spinel (AMS) support with different specific surface areas on the physicochemical properties and dynamics of the activation of Fe–K-containing catalysts in syngas atmosphere is studied. On the activation of Fe/AMS and Fe–K/AMS in a flow of CO/H₂ (1 : 1), Hägg carbide χ-Fe₅С₂ is formed with a Curie temperature T_θ = 257°С for all catalysts. However, using the magnetometric method in situ, it is found that the amount of carbide formed is different for aluminum magnesium spinel with different specific surface areas.
