A process for opening C5 and C6 rings without substantial cracking. A feedstream containing compounds comprised of at least one C5-ring, at least one C6-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. |
