Patent

CA 2519103

A processes is provided to inhibit or limit the decomposition of a halide- containing olefin oligomerization catalyst system during recovery of an oligomerization product. The process includes deactivation of an olefin oligomerization catalyst system present in an olefin oligomerization reactor effluent stream by contact with an alcohol under conditions that minimize potential for deactivated catalyst system decomposition. Such conditions include minimization of the water content of the deactivation agent and concentration of the deactivation agent.

L'invention concerne un procédé permettant d'inhiber ou de limiter la décomposition d'un système catalyseur d'oligomérisation oléfinique contenant des halogénures lors de la récupération d'un produit d'oligomérisation. Ledit procédé consiste à désactiver un système catalyseur d'oligomérisation oléfinique présent dans un courant d'effluent de réacteur d'oligomérisation oléfinique par contact avec un alcool dans des états qui minimisent le potentiel de décomposition du système catalyseur désactivé. Ces états comprennent notamment la minimisation de la teneur en eau de l'agent désactivant et la concentration dudit agent.
