Abstract
Process for preparing a self-regenerating catalyst, based on iron oxide as the main substituent, mixed with activating adjuvants for the dehydrogenation of olefins in dienes and alkylbenzenes in corresponding vinylbenzenes, characterized in that in order to achieve high selectivities, the porosity of the catalyst is increased by adding, in the wet catalyst mixture, before extrusion, polystyrene in the form of beads or extracted, of 0.1 to 0.5 mm preferably of 0.3 mm in proportion of 5 to 30% in weight, preferably 20% by weight, relative to the finished catalyst.
