PROCESS FOR FEEDING CATALYST TO FLUIDIZED BED FOR VAPOR PHASE POLYMERISATION.
摘要
<p>A process for feeding a powdery catalyst with a gas intermittently to a high-pressure fluidized bed reactor for the vapor phase polymerisation of olefin, wherein the cross section of a catalyst feed pipe is reduced midway through the pipe to thereby make continuous catalyst feed possible and prevent the formation of a lump polymer.</p>
