Abstract
The industrial catalyst for high temperature dehydrogenation of ethylbenzene based on iron and potassium oxides undergoes, under reaction conditions, essentially a transformation into magnetite, Fe3O4, and a mixture of ternary oxides containing trivalent iron, viz. K2Fe22O34 and KFeO2. The latter compound constitutes the outside of the catalyst particles and is indeed the catalytically active phase.
