Production of olefin from saturated hydrocarbon
Abstract
Abstract THIS INVENTION RELATES TO AN IMPROVED METHOD FOR THE CONTINUOUS PRODUCTION OF OLEFIN FROM SATURATED HYDROCARBON IN A FLUDIZED BED REACTOR COMPRISING A REACTING VESSEL AND HEATING VESSEL HAVING LOWER CHAMBER PROVIDED WITH APERFORATED PLATE THEREIN, AN UPPER CHAMBER AND AN INTERMEDIATE PORTION CONSISTING OF A PLURALITY OF CONDUIT FLUIDLY CONNECTED TO BOTH CHAMBERS IN SUCH AN ARRANGEMENT THAT THE REACTING VESSEL ENCLOSES AT LEAST THE CONDUITS OF THE HEATING VESSEL. TO EFFECT DEHYDROGENATION OF THE MATERIAL GAS IN THE REACTING VESSEL, A CIRCULATING STREAM CONTAINING SOLID PARTICLES FLUIDIZED AND HEATED BY A HEATING GAS FEED IS CREATED IN THE HEATING VESSEL, BETWEEN BOTH CHAMBERS THROUGHT THE CONDUITS, WHEREBY SUFFICIENT HEAT FOR THE DEHYDROGENATION IS CONTINUOUSLY TRANSFEERED FROM THE CIRCULATING STREAM IN THE HEATING VESSEL TO A FLUIDIZED CATALYST BED IN THE REACTING VESSEL THROUGH THE CONDUITS.
