Title
(EN) ON-LINE ADJUSTMENT OF MIXED CATALYST RATIO AND OLEFIN POLYMERIZATION
(FR) AJUSTEMENT DANS UNE CONDUITE DE RAPPORT DE CATALYSEUR MIXTE ET POLYMÉRISATION D'OLÉFINE
Abstract
(EN)
The present disclosure provides processes for polymerizing olefin(s). In at least one embodiment, a method for producing a polyolefin is provided. The method includes contacting a first composition and a second composition in a line to form a third composition. The first composition includes a contact product of a first catalyst, a second catalyst, a support, a first activator, and a diluent, and the mol ratio of first catalyst to second catalyst is from 90:10 to 40:60. The second composition includes a contact product of the second catalyst, a second activator, and a second diluent. The third composition includes a mol ratio of first catalyst to second catalyst of from 89:11 to 10:90. The method includes introducing the third composition from the line into a gas-phase fluidized bed reactor, exposing the third composition to polymerization conditions, and obtaining a polyolefin.

La présente invention concerne des procédés de polymérisation d'oléfine(s). Selon au moins un mode de réalisation, l'invention concerne un procédé de production d'une polyoléfine. Le procédé peut consister à mettre en contact une première composition et une deuxième composition dans une conduite pour former une troisième composition. La première composition comprend un produit de contact d'un premier catalyseur, d'un second catalyseur, d'un support, d'un premier activateur et d'un diluant, et le rapport molaire du premier catalyseur au second catalyseur s'inscrit dans la plage de 90:10 à 40:60. La deuxième composition comprend un produit de contact du second catalyseur, d'un second activateur et d'un second diluant. La troisième composition a un rapport molaire du premier catalyseur au second catalyseur s'inscrivant dans la plage de 89:11 à 10:90. Le procédé consiste à introduire la troisième composition à partir de la conduite dans un réacteur à lit fluidisé en phase gazeuse, à exposer la troisième composition à des conditions de polymérisation, et à obtenir une polyoléfine.
