Title (EN) REDUCED POLYMER FORMATION FOR SELECTIVE ETHYLENE OLIGOMERIZATIONS
(FR) FORMATION RÉDUITE DE POLYMÈRES POUR L'OLIGOMÉRISATION SÉLECTIVE DE L'ÉTHYLÈNE
Abstract:
(EN) Disclosed herein are processes, systems, and reaction systems for the oligomerization of ethylene to form an ethylene oligomer product in a reaction zone using a catalyst system having i) a chromium component comprising a heteroatomic ligand chromium compound complex of the type disclosed herein, and ii) an aluminoxane. A C3+ olefin can be present in the reaction zone for a period of time, where the C3+ olefin is not an ethylene oligomer formed in-situ within the reaction zone.
(FR) L'invention concerne des procédés, des systèmes et des systèmes réactionnels pour l'oligomérisation de l'éthylène afin de former un produit oligomère d'éthylène dans une zone réactionnelle à l'aide d'un système catalytique contenant : i) un constituant à base de chrome comprenant un complexe de composé de chrome à ligand hétéroatomique du type décrit ici, et ii) un aluminoxane. Une oléfine C3+ peut être présente dans la zone réactionnelle pendant un certain laps de temps, où l'oléfine C3+ n'est pas un oligomère d'éthylène formé in situ à l'intérieur de la zone réactionnelle.
