Title
(EN) OLEFIN GAS PHASE POLYMERISATION
(FR) POLYMÉRISATION D'OLÉFINES EN PHASE GAZEUSE
Abstract
(EN) The invention is directed to a process for the gas phase polymerisation of one or more olefin monomers in a fluidised bed reactor in a dry mode or in a (super) condensed mode with a gas stream comprising an inert gas characterised in that the inert gas comprises a mixture of inert components: (1) nitrogen; (2) a gas heat capacity increasing agent (3) a sorption promoting agent and (4) a polymer swelling agent. The inert gas may comprise (1 ) 5-60 % by mol nitrogen (2) 10- 90 % by mol ethane (3) 1 -50 % by mol % n-butane and (4) 0.1 -10 % by mol % n-pentane or iso-pentane.
(FR) L'invention concerne un procédé de polymérisation en phase gazeuse d'au moins un monomère d'oléfine dans un réacteur à lit fluidisé en mode à sec ou en mode super-condensé avec un flux de gaz comprenant un gaz inerte se caractérisant en ce qu'il comprend un mélange de composants inertes: (1) azote; (2) agent augmentant la capacité thermique d'un gaz (3) agent favorisant la sorption (4) agent de gonflement de polymère. Le gaz inerte peut comprendre (1) 5-60% en mol d'azote (2) 10-90% en mol d'éthane (3) 1-50% en mol en % de n-butane et (4) 0,1-10% en mol en % de n-pentane ou isopentane.
