Patent

CA 2415702

Disclosed is a process for opening naphthenic rings of naphthenic ring containing compounds, and catalysts which can be used in that process. The naphthene ring opening catalyst is a polymetallic catalyst comprising Group VIII metals. In a preferred embodiment the naphthene ring opening catalyst comprises Ir in combination with a Group VIII metal selected from at least one of Pt, Rh, and Ru, in an amount effective for opening a naphthene ring- containing compound at a tertiary carbon site.

L'invention concerne un procédé pour ouvrir des noyaux naphténiques de composés contenant des noyaux naphténiques, ainsi que des catalyseurs pouvant être utilisés dans ce procédé. Le catalyseur d'ouverture de noyau naphténique est un catalyseur comprenant des métaux de groupe VIII. Dans un mode de réalisation préféré, le catalyseur d'ouverture de noyau naphténique comprend de l'Ir en combinaison avec un métal du groupe VIII sélectionné parmi au moins un des métaux Pt, Rh, et Ru, en une quantité suffisante pour ouvrir un composé contenant des noyaux naphténiques au niveau d'un site de carbone tertiaire.
