DEHYDROGENATION CATALYST

摘要

The dehydrogenation catalyst consists of 50 to 95% by weight of an iron compound and 5 to 50% by weight of at least one promoter and/or at least one stabiliser. To prepare the catalyst, goethite, lepidocrocite, haematite, maghaemite, magnetite or mixtures of the said materials, having a specific surface area of from 1 to 150 m<2>/g, measured according to BET, are used as the iron compound and mixed or kneaded with the further component(s) and then moulded. The catalyst is used for dehydrogenating ethylbenzene to styrene.
