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 comprises Ir on a composite support of alumina and acidic silica-alumina molecular sie...

Beschreibung
Zusammenfassung:	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 comprises Ir on a composite support of alumina and acidic silica-alumina molecular sieve. Th e ring opening activity is not significantly deactivated by exposure to oxygen at greater than about 250 ~C.
