Title (EN) CATALYST SYSTEM USED IN OLEFIN OLIGOMERIZATION AND METHOD FOR OLEFIN OLIGOMERIZATION
(FR) SYSTÈME CATALYSEUR UTILISÉ DANS L'OLIGOMÉRISATION D'OLÉFINES ET PROCÉDÉ D'OLIGOMÉRISATION D'OLÉFINES
Abstract:
(EN) The invention relates to the field of oligomerization of olefins to produce linear α-olefins, in particular hexene-1, with the use of a catalyst system. The catalyst system comprises a chromium source compound, a nitrogen-containing ligand, alkylaluminum, and a zinc compound, wherein catalyst system is activated during its preparation by 1) heating some and SHF irradiation (microwave irradiation) of alkylaluminum or a mixture of the alkylaluminum and the zinc compound, or by 2) heating alkylaluminum or a mixture of the alkylaluminum and the zinc compound, followed by holding (aging) the prepared catalyst system for a certain period of time.
(FR) L'invention concerne le domaine de l'oligomérisation des oléfines pour obtenir des α-oléfines linéaires, en particulier du hexène-1, à l'aide d'un système catalyseur. Le système catalyseur comprend un composé source de chrome, un ligand contenant de l'azote, un alkylaluminium et un composé de zinc, le système catalyseur étant activé pendant sa préparation par 1) chauffage d'une partie, et exposition à des HF et SHF (exposition à des micro-ondes), de l'alkylaluminium ou d'un mélange de l'alkylaluminium et du composé de zinc, ou par 2) chauffage de l'alkylaluminium ou d'un mélange de l'alkylaluminium et du composé de zinc, suivi du maintien (vieillissement) du système catalyseur préparé pendant un certain laps de temps.
