摘要： A process for preparing polyethylene from "feed ethylene" comprises: a) a hydrogenation stage in which "feed ethylene" containing impurities or secondary components such as acetylene and ethane is reacted with hydrogen to remove the acetylene by catalytic hydrogenation to form ethylene and part of the ethylene is converted into ethane, and b) a polymerization stage in which the ethylene leaving stage a) is reacted in the gas phase in a fluidized-bed reactor to form polyethylene, where the fluidizing gas used comprises, on entering the reactor, ethene and from 20 to 70% by volume of ethane, based on the total volume of the fluidizing gas, possibly together with further components, where, in a), ethylene is converted in a targeted manner into ethane in addition to the ethane already present in the "feed ethylene" so that the concentration specified in b) results. An apparatus for carrying out the process is also provided. In the process claimed, ethane is used to increase the heat capacity of the fluidizing gas used.

摘要： An apparatus comprises a cyclone including an upper section (3a); a middle section (3b) having wall tapering in downward direction; a lower section (3c); and a tube (5) extending axially symmetrically down into (3a). The ratio of distance from lower end of tube extending downward into the cyclone to intersection of imaginary extension of wall of tube with wall of (3b) to diameter of tube is 3-8 (preferably 4-7). The apparatus further comprises a gas phase fluidized bed reactor, and a recycle gas line connected to the reactor for discharging and recirculating the recycle gas stream. The cyclone is located in the recycle gas line for reduction and precipitation of the solid particles entrained in the recycle gas from the reactor. An independent claim is included for a continuous gas phase polymerization process involving polymerizing olefins in gas phase in a bed of finely divided polymer in presence of catalyst at 0.1 - 15 Mpa pressure and at 30 - 150[deg]C in polymerization zone of polymerization reactor.
