PROCESS FOR SELECTIVELY OPENING NAPHTHENIC RINGS

PROCESS FOR SELECTIVELY OPENING NAPHTHENIC RINGS

A process for selectively opening naphthenic rings of naphthenic ring- containing compounds in a feedstream wherein at least about 50 wt.% of the ring compounds in the feedstream are characterized as containing at least one C6, ring having at least one substituent containing 3 or more carbon atoms....

Beschreibung
Zusammenfassung:A process for selectively opening naphthenic rings of naphthenic ring- containing compounds in a feedstream wherein at least about 50 wt.% of the ring compounds in the feedstream are characterized as containing at least one C6, 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 C10 paraffins; and b) a selectivity of at least 0.20, which selectivity i s defined as %C10 paraffin yield/%C10 ring disappearance.
