Abstract

Una rejilla de distribucion de gas que comprende una pluralidad de bandejas dispuestas para formar las paredes laterales de un cono invertido, estando dicha pluralidad de bandejas unidas unas a otras para formar dichas ranuras en el área de solapamiento de bandejas adyacentes. Reivindicacion 15: Un reactor de lecho fluidizado para la polimerizacion en fase gaseosa de alfa-olefinas, estando equipado dicho lecho fluidizado con una rejilla de distribucion de gas dispuesta en su base, un sistema de circulacion de gas para reciclar y enfriar el gas que no ha reaccionado desde la parte superior de dicho reactor a dicha rejilla de distribucion y un conducto para la descarga continua de polímero desde el reactor, caracterizado porque dicha rejilla de distribucion comprende una pluralidad de bandejas dispuestas para formar las paredes laterales de un cono invertido, estando dicha pluralidad de bandejas unidas unas a otras para formar ranuras en el área de solapamiento de bandejas adyacentes.
