    • A process for introducing a catalyst powder based on a titanium compound supported on magnesium halide into a gas-phase olefin polymerization reactor, characterized in that it comprises: (a) storing the catalyst powder under an atmosphere of a liquid C
      3 -C
      12 alkane; (b) withdrawing from step (a) a measured amount of said catalyst powder by means of a rotary valve; (c) transferring said metered amount of catalyst powder to a catalyst activation section by a continuous pick-up flow of a liquid C
      3 -C
      12 alkane; (d) contacting the catalyst powder with a liquid phase comprising an organo-aluminum compound and optionally an external donor compound, at a temperature ranging from -20 °C to 60 °C; (e) introducing the activated catalyst powder in one or more gas-phase olefin polymerization reactors, where a gaseous mixture comprising at least one alpha-olefin is subjected to polymerization.
    • 一种将负载在卤化镁上的钛化合物的催化剂粉末引入气相烯烃聚合反应器中的方法,其特征在于它包括:(a)将催化剂粉末储存在液体C 3 -C 12烷烃气氛下; (b)通过旋转阀从步骤(a)中取出测量量的所述催化剂粉末; (c)通过液体C 3 -C 12烷烃的连续吸入流将所述计量的催化剂粉末转移到催化剂活化部分; (d)在-20℃至60℃的温度下使催化剂粉末与包含有机铝化合物和任选的外部供体化合物的液相接触; (e)将活化的催化剂粉末引入一个或多个气相烯烃聚合反应器中,其中包含至少一种α-烯烃的气态混合物进行聚合。
