Title (EN) ETHYLENE GAS PHASE POLYMERISATION PROCESS
(FR) PROCÉDÉ DE POLYMÉRISATION EN PHASE GAZEUSE D'ÉTHYLÈNE
Abstract:
(EN) The invention relates to a gas phase polymerisation process for the production of ethylene polymers in the presence of a catalyst composition based on a chromium compound, a titanium compound and a silica support material. The silica support material has a surface area (SA) between 685 m2/g and 800 m2/g, a pore volume (PV) between 1.65 and 1.85 cm3/g and an average particle size in the range between 25 and 35 micrometres.The catalyst composition is injected by a dry catalyst feeder into the polymerization reactor.
(FR) L'invention concerne un procédé de polymérisation en phase gazeuse pour la production de polymères d'éthylène en présence d'une composition de catalyseur sur la base d'un composé de chrome, d'un composé de titane et d'un matériau support de silice. Le matériau support de silice a une surface spécifique (SA) entre 685 m2/g et 800 m2/g, un volume des pores (PV) entre 1,65 et 1,85 cm3/g et une taille moyenne de particule dans la plage comprise entre 25 et 35 micromètres. La composition de catalyseur est injectée par un dispositif d'alimentation en catalyseur sec dans le réacteur de polymérisation.
