    摘要: The present invention relates to an injector nozzle defining a passage for a flow of reactants to be injected into a loop reactor suitable for olefin slurry polymerization, consisting essentially of a fluid conduit extending into a discharge orifice portion to be connected to an opening in the reactor wherein the passage of the discharge orifice portion has a non-circular cross-section and the passage of the fluid conduit has a circular cross-section. The invention also relates to the use of the injector nozzle for injecting reactants into a loop reactor suitable for olefin polymerization reaction, wherein said injector nozzle is connected on an inner three quarter circle on or above an elbow section of the reactor.
