Potassium ferrate-containing catalyst for dehydrogenation of ethylbenzene to styrene

摘要

Catalysts for dehydrogenating ethylbenzene to styrene which comprise iron oxide, oxides of alkaline and alkaline-earth metals, oxides of the lanthanide series, oxides of metals of the sixth group, prepared from a paste of iron oxide impregnated with an aqueous solution of a cerium salt, treated with aqueous KOH and calcined, after drying, to preform potassium ferrate, to which the other components or precursors of the catalyst are then added.
