Abstract

MéTODO E APARELHO PARA A PRODUçãO DE POLìMEROS. A presente invenção refere-se a um método e aparelho para a produção de polímeros em um reator de polimerização de fase gasosa, o qual possui um corpo de reator alongado, e um eixo geométrico central disposto em um sentido essencialmente vertical. O reator compreende uma parte superior e uma parte inferior, as quais são separadas por uma chapa de distribuição, que promove a distribuição no leito fluidizado de monómeros que fluem da parte inferior para a parte superior. De acordo com a presente invenção, pelo menos uma parte da corrente de gás alimentada para a parte inferior do reator é conduzida ao longo do interior das paredes de reator pela chapa de distribuição a fim de impedir a formação de zonas de estagnação no leito fluidizado nas paredes de reator nas proximidades da chapa de distribuição.
