Abstract
A cyclical process is used to produce an olefinic hydrocarbon from paraffinic hydrocarbons. In the first step, the feed is contacted with a molybdenum-containing metal compound, e. g., iron, cobalt, or nickel molybdate, the step being conducted for a sufficient time to dehydrogenate the paraffinic hydrocarbon and at least partially reduce the molybdate to molybdite. In the second step, the molybdenum compound (at least partially reduced to the state of molybdite) is reoxidized to the molybdate form before it is contacted with additional paraffinic hydrocarbon, this reoxidation step being conducted by contacting the molybdite-containing compound with an oxygen-containing gas, essentially in the absence of paraffinic hydrocarbon. The first and second steps are repeated sequentially.
