CATALYST FOR DEHYDROGENATION OF ALKYL AROMATIC HYDROCARBON AND PROCESS FOR PRODUCING VINYL AROMATIC HYDROCARBON USING THE SAME

摘要

Disclosed is a catalyst for dehydrogenation of analkyl aromatic hydrocarbon, wherein the catalyst is an ironoxide catalyst and is produced by reducing iron oxidecontaining potassium oxide. The catalyst contains potassiumferrite, and has a ratio of a pore volume having a porediameter of from 20 to 100 nm to a pore volume having a porediameter of from 0 to 100 nm of between 0.7 and 0.9. Thecatalyst exhibits an excellent initial activity and has a longcatalyst life.
