Claim 1
Independent Claim
70 words
A PROCESS FOR THE OXIDATIVE DEHYDROGENATION OF ALIPHATIC HYDROCARBONS, WHICH COMPRISES CONTACTING AN ALIPHATIC FEED AND OXYGEN IN A REACTION ZONE AT A TEMPERATURE OF BETWEEN ABOUT 900*F. AND ABOUT 1300*F. WITH A CATALYST COMPRISING A MAJOR AMOUNT OF ALUMINUM PHOSPHATE AND A MINOR AMOUNT OF A HEAVY METAL OXIDE SELECTED FROM THE GROUP CONSISTING OF (A) MOLYBDENUM OXIDE, (B) VANADIUM PENTOXIDE, AND (C) A COMBINATION OF (A) AND (B).
Claim 2
