Title
(EN) LIGHT TREATMENT OF CHROMIUM CATALYSTS AND RELATED CATALYST PREPARATION SYSTEMS AND POLYMERIZATION PROCESSES
(FR) TRAITEMENT À LA LUMIÈRE DE CATALYSEURS À BASE DE CHROME AINSI QUE SYSTÈMES DE PRÉPARATION DE CATALYSEURS ET PROCESSUS DE POLYMÉRISATION ASSOCIÉS
Abstract
(EN)
Catalyst preparation systems and methods for preparing reduced chromium catalysts are disclosed, and can comprise irradiating a supported chromium catalyst containing hexavalent chromium with a light beam having a wavelength within the UV-visible light spectrum. Such reduced chromium catalysts have improved catalytic activity compared to chromium catalysts reduced by other means. The use of the reduced chromium catalyst in polymerization reactor systems and olefin polymerization processes also is disclosed, resulting in polymers with a higher melt index.

L'invention concerne des systèmes de préparation de catalyseurs et des procédés de préparation de catalyseurs à base de chrome réduits, et pouvant consister à exposer un catalyseur à base de chrome supporté contenant du chrome hexavalent à un faisceau de lumière ayant une longueur d'onde comprise dans le spectre de la lumière UV à la lumière visible. De tels catalyseurs à base de chrome réduits ont une activité catalytique améliorée par rapport à des catalyseurs à base de chrome réduits par d'autres moyens. L'invention concerne également l'utilisation du catalyseur à base de chrome réduit dans des systèmes de réacteurs de polymérisation et des processus de polymérisation d'oléfines, ce qui permet d'obtenir des polymères ayant un indice de fluidité plus élevé.
