| titleOfInvention | How to operate a polyolefin reactor |
| abstract | (57) [Abstract] [Purpose] When a polyolefin composed of a solid catalyst component containing titanium and / or vanadium and an organoaluminum compound is used to produce a polyolefin in a gas phase, Provided is a method for easily restarting operation when a polymerization reaction is stopped by introducing carbon dioxide gas into a reactor. [Structure] (1) A step of stopping the reaction by introducing carbon dioxide gas as a reaction terminator into the reaction system, (2) a step of discharging the introduced carbon dioxide gas to the outside of the system, and (3) Upon restarting the operation, a step of starting the reaction by first introducing an organoaluminum compound into the system is included, and the polymer particles are not discharged from the system from the termination of the reaction to the restart of the reaction. |
