Abstract

This is a catalyst and a process for partially hydrogenating polycyclic and monocyclic aromatic hydrocarbons such as benzene, naphthalenes, biphenyls, and alkylbenzenes to produce the corresponding cycloolefins. The catalyst is a hydrogenation catalyst comprising ruthenium and a promoter metal, such as cobalt, on a composite support. It is a process in which the product cycloolefin is produced in high yield and with high selectivity.
