Title
(EN) ON-LINE ADJUSTMENT OF MIXED CATALYST RATIO BY TRIM AND OLEFIN POLYMERIZATION WITH THE SAME
(FR) AJUSTEMENT EN LIGNE D'UN RAPPORT DE CATALYSEUR MIXTE PAR POLYMÉRISATION DE TRIMÉTHACRYLATE DE TRIMÉTHYLOPROPANE (TRIM) ET D'OLÉFINE AVEC CELUI-CI
Abstract
(EN)
In an 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, wherein: the first composition comprises a contact product of a first catalyst, a second catalyst, a support, and a diluent, wherein the mol ratio of second catalyst to first catalyst is from 60:40 to 40:60, the second composition comprises a contact product of the second catalyst and a second diluent; 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.
