Abstract

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 Tθ = 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.
