Oxidative dehydrogenation process

Claim 1

THE METHOD FOR DEHYDROGENATING IN A DEHYDROGENATION ZONE HYDROCARBONS OF 4 TO 8 CARBON ATOMS HAVING AT LEAST FOUR CONTIGUOUS NON-QUATERNARY CARBON ATOMS TO PRODUCE A DEHYDROGENATED PRODUCT HAVING THE SAME NUMBER OF CARBON ATOMS AND THE SME STRUCTURE WITH THE EXCEPTION OF THE REMOVED HYDROGEN ATOMS WHICH COMPRISES HEATING IN THE VAPOR PHASE AT A TEMPERATURE OF ABOVE 400* C. THE SAID HYDROCARBON WITH OXYGEN IN A MOLAR RATIO OF GREATER THAN ONE-FOURTH MOL OF OXYGEN PER MOL OF SAID HYDROCARBON, CHLORINE IN AN AMOUNT OF FROM .005 TO 0.25 MOL OF CHLORINE PER MOL OF SAID HYDROCARBON WITH THE CHLORINE BEING PRESENT IN AN AMOUNT OF NO GREATER THAN 40 MOL PERCENT OF THE TOTAL GASEOUS MIXTURE IN THE DEHYDROGENATION ZONE, THE RATIO OF THE MOLS OF SAID OXYGEN TO THE MOLS OF SAID CHLORINE BEING AT LEAST 2.0, THE FLOW REATE OF THE SAID HYDROCARBON IN THE SAID DEHYDROGENATION ZONE BEING BETWEEN 0.15 AND 15 VOLUMES OF HYDROCARBON PER VOLUME OF REACTOR SPACE CONTAINING CATALYST PER HOUR, THE PARTIAL PRESSURE OF SAID HYDROCARBON BEING EQUIVALENT TO LESS THAN ONE-HALF THE TOTAL PRESSURE IN THE PRESENCE OF A CATALYST COMPRISING AS ITS MAIN ACTIVE CONSTITUENT (1) A COMPOUND SELECTED FROM THE GROUP CONSISTING OF OXIDES, SALTS AND HYDROXIDES OF ALKALI AND ALKALINE EARTH METALS AND MIXTURES THEREOF, AND (2) A METAL OR COMPOUND THEREOF OF PERIODIC TABLE GROUP IB, THE SAID ALKALI AND ALKALINE EARTH METALS BEING PRESENT IN AN AMOUNT OF FROM ABOUNT .01 TO .5 ATOM PER ATOM OF THE METAL ELEMENTS OF THE SAID (2).

Claim 2

THE METHOD FOR DEHYDROGENATING IN A DEHYDROGENATION ZONE HYDROCARBONS OF 4 TO 8 CARBON ATOMS HAVING AT LEAST FOUR CONTIGUOUS NON-QUATERNARY CARBON ATOMS TO PRODUCE A DEHYDROGENATED PRODUCT HAVING THE SAME NUMBER OF CARBON ATOMS AND THE SME STRUCTURE WITH THE EXCEPTION OF THE REMOVED HYDROGEN ATOMS WHICH COMPRISES HEATING IN THE VAPOR PHASE AT A TEMPERATURE OF ABOVE 400* C. THE SAID HYDROCARBON WITH OXYGEN IN A MOLAR RATIO OF GREATER THAN ONE-FOURTH MOL OF OXYGEN PER MOL OF SAID HYDROCARBON, CHLORINE IN AN AMOUNT OF FROM .005 TO 0.25 MOL OF CHLORINE PER MOL OF SAID HYDROCARBON WITH THE CHLORINE BEING PRESENT IN AN AMOUNT OF NO GREATER THAN 40 MOL PERCENT OF THE TOTAL GASEOUS MIXTURE IN THE DEHYDROGENATION ZONE, THE RATIO OF THE MOLS OF SAID OXYGEN TO THE MOLS OF SAID CHLORINE BEING AT LEAST 2.0, THE FLOW REATE OF THE SAID HYDROCARBON IN THE SAID DEHYDROGENATION ZONE BEING BETWEEN 0.15 AND 15 VOLUMES OF HYDROCARBON PER VOLUME OF REACTOR SPACE CONTAINING CATALYST PER HOUR, THE PARTIAL PRESSURE OF SAID HYDROCARBON BEING EQUIVALENT TO LESS THAN ONE-HALF THE TOTAL PRESSURE IN THE PRESENCE OF A CATALYST COMPRISING AS ITS MAIN ACTIVE CONSTITUENT (1) A COMPOUND SELECTED FROM THE GROUP CONSISTING OF OXIDES, SALTS AND HYDROXIDES OF ALKALI AND ALKALINE EARTH METALS AND MIXTURES THEREOF, AND (2) A METAL OR COMPOUND THEREOF OF PERIODIC TABLE GROUP IB, THE SAID ALKALI AND ALKALINE EARTH METALS BEING PRESENT IN AN AMOUNT OF FROM ABOUNT .01 TO .5 ATOM PER ATOM OF THE METAL ELEMENTS OF THE SAID (2).
