Abstract: ISOBUTANE IS DEHYDROGENATED TO PRODUCE ISOBUTENE BY ESTABLISHING IN A FIRST O ZONE A DEHYDROGENATING AGENT CONSISTING ESSENTIALLY OF SULFUR AT 700-1000*C. AND THEN DIRECTLY CONTACTING SAME NON-CATALYTICALLY IN A SECOND ZONE AT 500-630*C. WITH ISOBUTANE. ESTABLISHMENT OF THE DEHYDROGENATING AGENT CAN BE DONE EITHER BY CATALYTICALLY REACTING SO2 AND H2S AT 700-1000*C. OR BY HEATING SULFUR TO 700-1000*C.
