Title (EN) THE PROCESS FOR PREPARATION OF $g(a)-OLEFINS
(FR) PROCEDE DE PREPARATION D'$g(a)-OLEFINES
Abstract:
(EN) The invention provides a process for preparing $g(a)-olefins. According to present invention, the high-pressure ethylene is fully used by utilizing a jet loop reactor during the stage of alykl chain growth reaction, and the selectivity of C6-10 olefins is enhanced by utilizing two-stage or multistage chain growth reaction in the process.
(FR) Procédé de préparation d'$g(a)-oléfines selon lequel l'éthylène à haute pression est totalement utilisé grâce à l'emploi d'un réacteur à jet à boucle de circulation pendant l'étape de réaction de croissance de la chaîne alkyle, et la sélectivité des oléfines C6-10 est améliorée par le recours à une réaction de croissance de chaîne à deux étapes ou à étapes multiples.
