Title (EN) CHROMIUM OXIDE CATALYST FOR ETHYLENE POLYMERIZATION
(FR) CATALYSEUR À BASE D'OXYDE DE CHROME POUR LA POLYMÉRISATION D'ÉTHYLÈNE
Abstract:
(EN) The invention relates to a solid catalyst system comprising a chromium compound, a metal compound, an aluminium compound and a silicon oxide support, wherein the silicon oxide support has an average particle diameter in the range between ≥20 and ≤50 μm, a pore volume in the range between ≥1.7 ml/g and ≤3 ml/g, and a surface area in the range between ≥400 m2/g and ≤800 m2/g and wherein the aluminium alkoxide compound has the formula R1-AI-OR2 wherein R1 is selected from (C1-C8) alkyl groups and OR2 is selected from (C1-C8) alkoxyl groups.
(FR) L'invention concerne un système catalyseur solide comprenant un composé de chrome, un composé métallique, un composé d'aluminium et un support d'oxyde de silicium, le support d'oxyde de silicium ayant un diamètre de particule moyen dans la plage entre ≥ 20 et ≤ 50 µm, un volume de pore dans la plage entre ≥ 1,7 ml/g et ≤ 3 ml/g, et une surface dans la plage entre ≥ 400 m2/g et ≤ 800 m2/g et le composé alcoxyde d'aluminium ayant la formule R1-AI-OR2 dans laquelle R1 est sélectionné parmi des groupes alkyle en C1-C8 et OR2 est sélectionné parmi des groupes alcoxyle en C1-C8.
