ABSTRACT:
Naphthenic rings in naphthenic ring-containing compounds in a feedstream are selectively opened wherein at least about 50 wt. % of the ring compounds in the feedstream are characterized as containing at least one C.sub.6 ring having at least one substituent containing 3 or more carbon atoms. The naphthenic rings are opened without significant dealkylation of any pendant substituents on the ring. The feedstream, containing such compounds, is contacted with a supported catalyst containing a metal selected from Ir, Ru, or a mixture thereof, which catalyst when reacted with a feed comprised of 20 wt. % n-butylcyclohexane in heptane diluent will result in: a) at least a 10% yield of C.sub.10 paraffin yield/%C.sub.10 ring disappearance.
