Реферат: Disclosed is a catalyst for dehydrogenation of an alkyl aromatic hydrocarbon, wherein the catalyst is an iron oxide catalyst and is produced by reducing iron oxide containing potassium oxide. The catalyst contains potassium ferrite, and has a ratio of a pore volume having a pore diameter of from 20 to 100 nm to a pore volume having a pore diameter of from 0 to 100 nm of between 0.7 and 0.9. The catalyst exhibits an excellent initial activity and has a long catalyst life.
