    摘要: A process for opening C.sub.5 and C.sub.6 rings without substantial cracking. A feedstream containing compounds comprised of at least one C.sub.5 -ring, at least one C.sub.6 -ring, or both, is contacted, in the presence of hydrogen, with a transition metal catalyst selected from the group consisting of carbides, nitrides, oxycarbides, oxynitrides, and oxycarbonitrides. The transition metal is selected from the group consisting of metals from Groups IVa, Va, and VIa of the Periodic Table of the Elements.

    摘要: The present invention relates to multi-metallic catalyst compositions for improved coke resistance in a hydrocarbon feed pre-reformer unit that comprises nickel and an enhancing component selected from at least one member of the group consisting of ruthenium, palladium, platinum, rhodium, cobalt, gold and silver on a support. The present invention further relates to a catalyst system for improved coke and sulfur resistance in a hydrocarbon feed pre-reformer unit that comprises at least one multi-metallic catalyst composition comprising nickel and an enhancing component selected from at least one member of the group consisting of ruthenium, palladium, platinum, rhodium, cobalt, gold and silver on a support used in conjunction with at least one sulfur capturing component selected from the group comprising copper oxide and zinc oxide. Finally the present invention relates to the use of this catalyst system in a process for pre-reforming a hydrocarbon feed stream.
