ABSTRACT:
A catalyst suitable for partially hydrogenating aromatic olefins to cyclohexene is disclosed. The catalyst is composed on a metallic active component deposited on a bi-oxide of gallium oxide-zinc oxide, and the metallic active component is selected from group VIII of the period table. The characteristic of the catalyst comprises a higher selectivity and yield in preparing cyclohexene.
