PROCESS FOR FEEDING CATALYST TO FLUIDIZED BED FOR VAPOR PHASE POLYMERISATION |
摘要 |
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.
