| titleOfInvention | Gas dispersion plate for gas phase polymerization equipment |
| abstract | PROBLEM TO BE SOLVED: To provide a gas dispersion plate which is provided in a fluidized bed polymerization vessel for performing gas phase polymerization of olefins and has an excellent action of uniformly dispersing a gas flow in a fluidized bed region. SOLUTION: In a gas dispersion plate provided in a fluidized bed polymerization vessel for performing gas phase polymerization of olefins and having a large number of gas passage holes, when the inner radius of the straight body portion of the polymerization vessel is set to 1, the straight body is Starting from the center of the part, the average diameter of the holes present on the outer periphery of the dispersion plate from 0.7 to 1.0 from the center is calculated as the average of the holes present on the inner periphery of the dispersion plate less than 0.7 from the center. It is characterized in that it is set larger than the diameter. This makes it possible to stably disperse the gas flow uniformly in the fluidized bed region of the polymerization vessel, effectively prevent formation of a dead zone, and also effectively prevent adhesion of the polymer to the polymerization vessel wall.
