DEHYDROGENATION CATALYST FOR ALKYL AROMATIC COMPOUNDS HAVING HIGH REDOX CATALYSIS, PROCESS FOR PREPARATION OF THE CATALYST AND PROCESS OF DEHYDROGENATION WITH THE SAME

摘要

The object of the present invention is to provide the catalyst used in a process for preparation of alkenylaromatic compounds by dehydrogenating alkyl aromatic compounds by means of steam as a diluent, wherein the catalyst prevents the block and corrosion caused by the alkali metal component migrated from the catalyst, and the process for producing same, and the dehydrogenation method using it.;The solid catalyst which has the high redox ability and comprises no alkali metal component migrated from the catalyst in the presence of steam with high temperature is used.
