Naphthene ring opening over an iridium ring opening catalyst
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 comprising Ir on a composite support of alumina and acidic silica-alumina molecular sieve. The ring opening activity is not significantly deactivated by exposure to oxygen at greater than about 250&deg; C.
