The invention relates to a catalyst for dehydrogenating hydrocarbons based on iron oxide and a method for producing said catalyst. The catalyst contains at least one iron compound, at least one potassium compound, and 11 to 24 wt% of at least one cerium compound, calculated as CeO2, wherein the at least one iron compound and the at least one potassium compound are present at least partially in the form of one or more K/Fe mixed-oxide phases of the general formula KxFeyOz, wherein x is a number from 1 to 17, y is a number from 1 to 22, and z is a number from 2 to 34, and wherein the catalyst contains at least 50 wt%, with respect to the total catalyst, of the K/Fe mixed-oxide phases. The invention further relates to a method for producing said catalyst. |
