Abstract
A process is used to dehydrogenate organic compounds to a higher degree of unsaturation by contacting in a first step, the organic compound with a calcined zinc titanate catalyst. In the second step, the catalyst is contacted with oxygen essentially in the absence of the dehydrogenatable organic compound. The first and second steps are repeated sequentially.
Claims16
A process for catalytically dehydrogenating a dehydrogenatable hydrocarbon feedstock having at least one ##STR2## grouping which comprises:
- contacting said feedstock with a regenerable dehydrogenation catalyst in the substantial absence of free oxygen under dehydrogenation conditions wherein said regenerable dehydrogenation catalyst is prepared by calcining a mixture of zinc oxide and titanium dioxide at a temperature in the range of from about 650.degree. to about 1050.degree. C.
