A study of the action of magnesium on iron oxide catalysts for dehydrogenation of ethylbenzene to styrene

Mossbauer study of the action of magnesium on iron oxide catalysts for the dehydrogenation of ethylbenzene to styrene has been carried out systematically. The presence of opportune amount of Mg enhances the stability and dispersivity of catalysts. Therefore Mg is one kind of useful structure promoter.
