Title (EN) METHOD OF PRODUCING POLYETHYLENE AND POLYETHYLENE THEREOF
(FR) PRODUCTION DE PRODUCTION DE POLYÉTHYLÈNE ET POLYÉTHYLÈNE ASSOCIÉ
Abstract:
(EN) A system and method of producing polyethylene, including: polymerizing ethylene in presence of a catalyst system in a reactor to form polyethylene, wherein the catalyst system includes a first catalyst and a second catalyst; and adjusting reactor conditions and an amount of the second catalyst fed to the reactor to control melt index (MI), density, and melt flow ratio (MFR) of the polyethylene.
(FR) Cette invention concerne un système et un procédé de production de polyéthylène, comprenant : la polymérisation d'éthylène en présence d'un système de catalyseurs dans un réacteur pour former du polyéthylène, le système de catalyseurs comprenant un premier catalyseur et un second catalyseur; et l'ajustement des conditions de réacteur et de la quantité du second catalyseur introduite dans le réacteur pour contrôler l'indice de fluidité (MI), la densité, et l'indice de fluidité en masse (MFR) du polyéthylène.
