Oxidative dehydrogenation in the presence of chlorine

Claim 1

THE METHOD FOR DEHYDROGENATING HYDROCARBON COMPOUNDS HAVING 2 TO 20 CARBON ATOMS TO PRODUCE A DEHYDROGENATED PRODUCT HAVING THE SAME NUMBER OF CARBON ATOMS AND THE SAME 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 COMPOUND HAVING A >CH-CH< GROUP WITH OXYGEN IN A MOLAR RATIO OF GREATER THAN ONEFOURTH MOL OF OXYGEN PER MOL OF SAID HYDROCARBON COMPOUND, CHLORINE IN AN AMOUNT OF LESS THAN 0.3 MOL OF CHLORINE PER MOL OF SAID HYDROCARBON COMPOUND AND IN AN AMOUNT OF NO GREATER THAN 10 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 PARTIAL PRESSURE OF SAID HYDROCARBON COMPOUND 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) AN INORGANIC COMPOUND OF A METAL SELECTED FROM THE PERIODIC TABLE GROUP IIIB THE ATOMS OF THE SAID ALKALI AND ALKALINE EARTH METALS OF (1) BEING AT LEAST ABOUT 0.001 ATOM PER ATOM OF THE SAID METALS OF GROUP IIIB AND FURTHER THE SAID (1) BEING PRESENT IN AN AMOUNT OF UP TO 50 WEIGHT PERCENT OF THE TOTAL WEIGHT OF THE SAID (1) AND (2) WIHT THE WEIGHT PERCENT OF THE CATIONS OF THE DEFINED (1) AND (2) BEING AT LEAST 51 PERCENT OF ANY CATIONS IN THE CATALYST SURFACE EXPOSED TO THE REACTION GASES.

Claim 2

THE METHOD FOR DEHYDROGENATING HYDROCARBON COMPOUNDS HAVING 2 TO 20 CARBON ATOMS TO PRODUCE A DEHYDROGENATED PRODUCT HAVING THE SAME NUMBER OF CARBON ATOMS AND THE SAME 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 COMPOUND HAVING A >CH-CH< GROUP WITH OXYGEN IN A MOLAR RATIO OF GREATER THAN ONEFOURTH MOL OF OXYGEN PER MOL OF SAID HYDROCARBON COMPOUND, CHLORINE IN AN AMOUNT OF LESS THAN 0.3 MOL OF CHLORINE PER MOL OF SAID HYDROCARBON COMPOUND AND IN AN AMOUNT OF NO GREATER THAN 10 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 PARTIAL PRESSURE OF SAID HYDROCARBON COMPOUND 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) AN INORGANIC COMPOUND OF A METAL SELECTED FROM THE PERIODIC TABLE GROUP IIIB THE ATOMS OF THE SAID ALKALI AND ALKALINE EARTH METALS OF (1) BEING AT LEAST ABOUT 0.001 ATOM PER ATOM OF THE SAID METALS OF GROUP IIIB AND FURTHER THE SAID (1) BEING PRESENT IN AN AMOUNT OF UP TO 50 WEIGHT PERCENT OF THE TOTAL WEIGHT OF THE SAID (1) AND (2) WIHT THE WEIGHT PERCENT OF THE CATIONS OF THE DEFINED (1) AND (2) BEING AT LEAST 51 PERCENT OF ANY CATIONS IN THE CATALYST SURFACE EXPOSED TO THE REACTION GASES.
