CATALYST FOR DEHYDROGENATION OF ALKYL AROMATIC COMPOUND WHICH HAS IMPROVED PHYSICAL PROPERTIES, METHOD FOR PRODUCTION OF THE CATALYST, AND DEHYDROGENATION METHOD

摘要

A high cerium-containing dehydrogenation catalyst of alkyl aromatic compounds used in industrial scale, comprising iron oxide and potassium oxide, having improved physical strength of catalytic pellets, and a method for producing the catalyst, and the dehydrogenation method using the catalyst are disclosed. In producing high cerium-containing pellets by using a dehydrogenation catalyst comprising iron oxide and potassium oxide, cerium carbon hydroxide or a mixture of cerium carbon hydroxide and other cerium compounds is used as a cerium source to produce catalytic pellets having improved physical strength.
