CA 2402072
The present invention relates to a method for reducing/suppressing sheeting or agglomerates during polymerisation of olefins, especially during the fluidised bed gas phase polymerisation of olefins. In particular, the present invention relates to a method for reducing/suppressing sheeting or agglomerates during the product grade transition and/or catalyst transitions occuring polymerisation of olefins.
L'invention concerne un procédé de réduction/suppression de la mise en nappe ou en agglomérats au cours de la polymérisation d'oléfines, en particulier pendant la polymérisation à phase de gaz à lit fluidifié d'oléfines. L'invention concerne en particulier un procédé permettant de réduire/supprimer la mise en nappe ou en agglomérats lors de la transition de niveau de produit et/ou des transitions de catalyse se produisant au cours de la polymérisation d'oléfines.
