ABSTRACT:
A C.sub.8 cyclic olefin stream resulting from the dimerization of butadiene is dehydrogenated for highly selective preparation of ethyl benzene and hydrogen by directing a reactant stream consisting of a major amount of an inert gas such as nitrogen and a minor amount of said C.sub.8 cyclic olefin through a reaction zone having a cobalt molybdate on alumina catalyst containing 0.9-3% potassium oxide. The ethyl benzene is of suitable purity for manufacture of styrene therefrom.
