Abstract
AN IMPROVED PROCESS AND SYSTEM FOR THE ENDOTHERMIC DEHYDROGENATION OF AN ALKANE STREAM (1) IS DESCRIBED. THE PROCESS AND SYSTEM OF THE PRESENT INVENTION COMPRISE A BACK-MIXED FLUIDIZED BED REACTOR (4). THE ALKANE STREAM (1) IS DEHYDROGENATED IN A SINGLE REACTOR STAGE BY CONTACTING THE ALKANE STREAM (1) WITH A BACK-MIXED FLUIDIZED BED (44) OF CATALYST. DEACTIVATED CATALYST (38) IS WITHDRAWN FROM THE BACK-MIXED FLUIDIZED BED REACTOR (4) AND HEATED TO PRODUCE HOT REGENERATED CATALYST (36). THE HOT REGENERATED CATALYST (36) IS RETURNED TO THE BACK-MIXED FLUIDIZED BED REACTOR (4) AT A SUFFICIENT TO MAINTAIN THE BACK-MIXED FLUIDIZED BED REACTOR (4) AT A SUBSTANTIALLY ISOTHERMAL CONDITIONS.
