Abstract

Изобретение относится к устройству для газофазной полимеризации олефина(ов) и способу ее осуществления. Устройство состоит из реактора с псевдоожиженным слоем по меньшей мере одного патрубка для удаления полимера, снабженного изолирующим краном и соединяющего вертикальную боковую стенку реактора с воронкой-затвором, причем указанный патрубок отходит от вертикальной боковой стенки реактора в направлении сверху вниз таким образом, что образует с горизонтальной плоскостью угол А, составляющий 35-90°. Непрерывная газофазная полимеризация олефина(ов) осуществляется в реакторе с псевдоожиженным слоем, в котором предусмотрено удаление полимера через вертикальную боковую стенку реактора в воронку-затвор по разгрузочному патрубку таким образом, что перемещение полимера в разгрузочный патрубок производится сверху вниз в наклонном направлении, составляющем с горизонтальной плоскостью угол А, по меньшей мере равный углу естественного откоса β для полимера. Изобретение позволяет повысить степень заполнения воронки-затвора и уменьшить количество газа, удаляемого с полимером.
