processo e aparelho para a polimerização de olefinas. é apresentado um processo e um aparelho para a polimerização em fase gasosa de olefinas em um reator de leito fluidizado. o processo e o aparelho utilizam um ejetor de finos orientado verticalmente para reduzir a incrustação e o tempo de parada do reator. A process and apparatus for gas phase polymerization of olefins in a fluidized bed reactor are disclosed. The process and apparatus employ a vertically oriented fines ejector in order to reduce fouling and reactor downtime.
