    • The present invention deals with an olefin polymerisation process. At least one olefin is polymerised in gas phase in a fluidised bed in the presence of an olefin polymerisation catalyst in a polymerisation reactor having a vertical body; a generally conical downwards tapering bottom zone; a generally cylindrical middle zone above and connected to said bottom zone; and a generally conical upwards tapering top zone above and connected to said middle zone. Fluidisation gas is introduced to the bottom zone of the reactor from where it passes upwards through the reactor, and withdrawn from the top zone of the reactor. The gas is then compressed, cooled and returned into the bottom zone of the reactor. A fluidised bed is thus formed within the reactor where the growing polymer particles are suspended in the upwards rising gas stream wherein the superficial velocity of the fluidisation gas is less than the transport velocity of the particles. There is no fluidisation grid in the reactor. The fluidisation gas is passed from an inlet chamber into the bottom zone and the gas flows from the upper part of the inlet chamber to the lower part thereof and the gas flows from the lower part of the inlet chamber to the bottom zone.
    • 本发明涉及烯烃聚合方法。 在具有垂直体的聚合反应器中,在烯烃聚合催化剂存在下,在流化床中将至少一种烯烃在气相中聚合; 大致圆锥形的向下锥形底部区域; 在所述底部区域上方并与之连接的大致圆柱形的中间区域 以及在所述中间区域上方并连接到所述中间区域的大致圆锥形的向上锥形顶部区域。 将流化气体引入反应器的底部区域,从其向上通过反应器,并从反应器的顶部区域排出。 然后将气体压缩,冷却并返回到反应器的底部区域。 因此,在反应器内形成流化床,其中生长的聚合物颗粒悬浮在向上升的气流中,其中流化气体的表观速度小于颗粒的输送速度。 反应器中没有流化网。 流化气体从入口室进入底部区域,并且气体从入口室的上部流动到其下部,并且气体从入口室的下部流动到底部区域。
