Title
(EN) OLEFIN OLIGOMERIZATION PROCESS
(FR) PROCÉDÉ D'OLIGOMÉRISATION D'OLÉFINES
Abstract
(EN)
The invention relates to an olefin oligomerization process comprising the steps of: i) contacting a feed comprising olefins and nitrileswith a guard bed comprising eta alumina; and ii) contacting the feed obtained in step i) with an oligomerization catalyst under conditions suitable to oligomerize the olefins in the feed. It also relates to the use of a guard bed comprising eta-alumina for reducing the content of basic organic compounds in a hydrocarbon feed.
(FR)
L'invention concerne un procédé d'oligomérisation d'oléfines qui comprend les étapes suivantes : i) la mise en contact d'une alimentation comprenant des oléfines et des nitriles avec un lit de garde comprenant une alumine êta ; et ii) la mise en contact de l'alimentation obtenue à l'étape i) avec un catalyseur d'oligomérisation dans des conditions appropriées pour oligomériser les oléfines dans l'alimentation. L'invention concerne également l'utilisation d'un lit de garde comprenant de l'alumine êta pour réduire la teneur en composés organiques basiques dans une alimentation hydrocarbonée.
