摘要： The invention concerns a method of producing catalysts, containing iron and potassium and optionally other elements, suitable for the selective dehydrogenation of hydrocarbons to give the corresponding olefinically unsaturated hydrocarbons. In a first step, a finely particulate dry or aqueous mixture of an iron compound with a potassium compound and optionally also compounds of other elements is calcined in such a way that 5 to 50 mu m diameter conglomerates, made up of smaller particles, are produced. In a second step, preferably following shaping, the mixture is calcined at 300 to 1000 DEG C, the maximum calcining temperature in the second step preferably being at least 30 DEG C lower than that in the first step. The invention also concerns the use of the catalysts produced in this way, particularly in the dehydrogenation of ethylbenzene to styrene.
