Sulfur promoted oxidative dehydrogenation of organic compounds

Abstract

Abstract ORGANIC COMPOUNDS HAVING A DEHYDROGENATABLE CARBONCARBON BOND ARE DEHYDROGENATED IN THE VAPOR PHASE BY CONTACT WITH A MIXTURE OF SULFUR CONTAINING COMPOUNDS AND OXYGEN OR AN OXYGEN CONTAINING MIXTURE, THE OXYGEN BEING INTRODUCED THROUGHOUT THE REACTION ZONE IN SATGE INCREMENTS, EACH INCREMENT BEING INSUFFICIENT TO CAUSE SUBSTANTIAL BURNING OF THE ORGANIC FEED, THE REACTION BEING PREFERABLY EFFECTED IN THE PRESENCE OF A SUITABLE LOW SURFACE AREA CATALYST AND AN INERT DILUETN; THE SULFUR CONTAINING COMPOUNDS USED IN THE REACTION ARE COMPRISED OF THOSE WHICH (I) REACT WITH THE ORGANIC FED TO YIELD HYDROGEN SULFIDE OR SULFUR AND/OR (II) REACT WITH OXYGEN TO YIELD SULFUR OXIDE AND/OR SULFUR. THESE COMPOUNDS CANNOT ONLY BE ADDED ALL AT THE FEED INLET BUT MAY ALSO BE ADDED TO THE REACTION ZONE IN A STAGED MANNER, I.E., BOTH AT THE FEED INLET AND IN INCREMENTS DOWNSTREAM OF THE FEED INLET, TO MIMIMIZE UNDESIRABLE HEAVY PRODUCT FORMATION AND CATALYST DEACTIVATION.
