| titleOfInvention | Gas phase polymerization of olefins |
| abstract | (57) Abstract: In a continuous gas phase polymerization reaction of olefins using a fluidized bed reactor having a solid catalyst inlet, a polymer outlet, and a gas circulation system, (1) the solid catalyst used is Based on the properties, set the allowable limit concentration of scattered particles to the gas circulation system, (2) measure the particle concentration of solids in the circulating gas with a gas analyzer installed in the gas circulation system, (3) The measured value is compared with the allowable limit concentration, and (4) when the measured value exceeds the allowable limit concentration, the operating condition is changed so as to be lower than the allowable limit concentration. A continuous gas phase polymerization method for olefins. [Effect] In the gas phase polymerization of olefin, the amount of particles scattered from the reactor to the circulation system is reduced, and there is no trouble such as adhesion and blockage in the gas circulation system, and stable operation can be performed for a long period of time. Troubles can be solved by taking early measures in advance. |
