    • The present invention deals with a process of producing a polymer of at least one olefin in two consecutive reactors in gas phase in the presence of an olefin polymerisation catalyst where an olefin is polymerised in a first polymerization reactor in the presence of an olefin polymerisation catalyst and a first reaction gas mixture to form a fluidized bed comprising an olefin polymer and said first reaction gas mixture. The first reaction gas mixture together with the olefin polymer is continuously or intermittently withdrawn from the first polymerisation reactor and directed into a separation vessel so that a bed of polymer is formed in said separation vessel. A portion of said first reaction gas mixture is withdrawn from said separation vessel and returned into the first polymerization reactor to a point where the pressure is lower than in the separation vessel. The olefin polymer is withdrawn from said separation vessel to form a second product stream and the second product stream is directed into a second polymerization reactor. A second gas may be introduced into the bottom part of the separation vessel to avoid the carry-over of the reactants from the first polymerisation stage into the second polymerisation stage.
    • 本发明涉及一种在烯烃聚合催化剂存在下,在两相连续反应器中制备至少一种烯烃聚合物的方法,其中烯烃在烯烃聚合催化剂存在下在第一聚合反应器中聚合, 第一反应气体混合物以形成包含烯烃聚合物和所述第一反应气体混合物的流化床。 将第一反应气体混合物与烯烃聚合物一起连续地或间歇地从第一聚合反应器中取出并引导到分离容器中,使得在所述分离容器中形成聚合物床。 将所述第一反应气体混合物的一部分从所述分离容器中取出并返回到第一聚合反应器中至压力低于分离容器的点。 从所述分离容器中取出烯烃聚合物以形成第二产物流,将第二产物流引入第二聚合反应器。 可以将第二气体引入分离容器的底部,以避免反应物从第一聚合阶段进入第二聚合阶段。
