Abstract: A PROCESS FOR THE PRODUCTION OF STYRENE BY CATALYTIC DEHYDROGENATION OF ETHYLBENZENE WITH OXYGEN OF A GAS CONTAINING MOLECULAR OXYGEN IN THE PRESENCE OF STEAM IN A FLUIDIZED BED AT A TEMPERATURE OF FROM 350* TO 600*C. USING A SOLID CATALYST AND REGENERATING THE CATALYST BY BURNING OFF THE CARBONACEOUS DEPOSITS, WHICH COMPRISES CARRYING OUT THE REGENERATION OF THE CATALYST, WITH INCOMPLETE BURNING OFF OF THE CARBONACEOUS DEPOSITS WITH OXYGEN OR A GAS CONTAINING MOLECULAR OXYGEN, ONLY TO SUCH AN EXTENT THAT ON AN AVERAGE THE CATALYST CONTAINS DURING THE REACTION FROM 1 TO 30% BY WEIGHT OF THESE CARBONACEOUS DEPOSITS WITH REFERENCE TO THE CATALYST. STYRENE IS A VALUABLE MONOMER FOR THE PRODUCTION OF PLASTICS.
