MIXED OXIDES CATLYSTS FOR DEHYDROGENATION OF ETHYLBENZENE TO STYRENE

摘要

PURPOSE: A multiple oxide catalyst manufacturing styrene by dehydrogenation of ethylbenzene is provided to maintain activity and stability of the catalyst and to accomplish a high styrene conversion ratio without using steam. CONSTITUTION: A multiple oxide catalyst manufacturing styrene by dehydrogenation of ethylbenzene includes a titania - zirconia two metal oxide catalyst supporter and iron oxide, vanadium oxide or cerium oxide. The titania - zirconia two metal oxide catalyst supporteris manufactured by coprecipitation. The iron oxide, vanadium oxide or cerium oxide is mounted at the catalyst support at the same time.
