Patent

CA 2748877

A process for the double-bond isomerization of olefins is disclosed. The process may include contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst to convert at least a portion of the olefin to its isomer. The isomerization catalysts disclosed herein may have a reduced cycle to cycle deactivation as compared to conventional catalysts, thus maintaining higher activity over the complete catalyst life cycle.

L'invention porte sur une isomérisation de la double liaison d'oléfines. Le procédé peut comprendre la mise en contact d'un courant de fluide comprenant des oléfines avec un lit fixe comprenant un catalyseur d'isomérisation oxyde métallique basique activé pour convertir au moins une partie de l'oléfine en son isomère. Les catalyseurs d'isomérisation décrits ici peuvent avoir une désactivation cycle à cycle réduite par comparaison avec des catalyseurs classiques, permettant ainsi de maintenir une activité supérieure sur le cycle de vie complet du catalyseur.
