OLEFIN GAS PHASE POLYMERISATION |
摘要 |
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. |
