摘要
The gas-phase fluidized-bed reactor conducting reaction by feeding a gas, through a gas-distribution plate located at the lower part of a reaction vessel, into a fluidized bed formed on the gas-distribution plate, wherein the reaction vessel is made up so as to have a narrowed part at a specified position of the gas flow passage above the gas-distribution plate, and the fluidized bed is formed in the area from below the narrowed part to above the narrowed part. The gas-phase fluidized bed rector of the present invention allows manufacturing polymers having excellent homogeneity of polymer structure in gas-phase polymerization.
