Naphthene ring opening over a ring opening catalyst combination
Disclosed is a process for opening naphthenic rings of naphthenic ring-containing compounds, along with catalysts which can be used in that process. The ring opening is accomplished using a ring opening catalyst system which combines an Ir ring opening catalyst with a Pt and Pd catalyst. The combination of the Pt and Pd-containing catalyst with an Ir-containing catalyst incorporates desirable isomerization activity and also results in substantial ring opening activity that enables Ir to be loaded at a level that is substantially below that of Ir-only ring opening processes.
