VAPOR PHASE POLYMERIZATION OF OLEFIN, SOLID CATALYST COMPONENT SUPPLYING DEVICE, AND FLUIDIZED BED REACTOR

摘要

PROBLEM TO BE SOLVED: To provide a method for performing a vapor phase polymerization of an olefin capable of performing the vapor phase polymerization stably for a long period of time without clogging a catalyst supplying nozzle even by supplying a highly active catalyst, and hardly generating a local reaction in a fluidized bed, and also provide a nozzle for supplying the catalyst and a fluidized bed reactor enabling the vapor phase polymerization of the olefin. SOLUTION: The method produces polyolefins by performing a vapor phase polymerization of an olefin and supplies the olefin into the fluidized bed reactor maintaining polymer particles containing a solid catalyst component in a fluidized state. The method performs the vapor phase polymerization of the olefin by supplying the solid catalyst component from a supplying port into the fluidized bed reactor, while supplying an inactive medium in the vicinity of the supplying port of the solid catalyst component.
