  • Process and catalyst for partially hydrogenating aromatics to produce cycloolefins
    Patent number: 5424264
    Abstract: This is a catalyst and a process for partially hydrogenating polycyclic and monocyciic aromatic hydrocarbons such as benzene, naphthalenes, biphenyls, and alkylbenzenes to produce the corresponding cyclooiefins. The catalyst is a hydrogenation catalyst comprising ruthenium on a composite support. It is a process in which the product cycloolefin is produced in high yield and with high selectivity.
    Type: Grant
    Filed: March 11, 1994
