Abstract

The present invention relates to a catalyst based on iron oxide for the dehydrogenation of hydrocarbons and also a process for producing it. The catalyst comprises at least one iron compound, at least one potassium compound and at least one cerium compound, wherein the at least one iron compound and the at least one potassium compound are at least partly present in the form of one or more K/Fe mixed oxide phases of the general formula KxFeyOz, where x is from 1 to 17; y is from 1 to 22 and z is from 2 to 34, where the catalyst comprises at least 20% by weight, based on the total catalyst, of the K/Fe mixed oxide phases and comprises crystalline cerium dioxide having a crystallite size in the range from 10 nm to 30 nm.
