The present invention relates to a commercialization reaction process for selective oligomerization of ethylene, and more particularly, to a process for efficiently removing reaction heat generated in a reaction and controlling a temperature of a reactor, and more particularly, , The unreacted ethylene is separated from the circulating stream through a device for separating unreacted ethylene from the resulting circulating stream, and the remaining mixture is cooled and reintroduced into the reactor to remove the reaction heat in the reactor and to adjust the temperature by oligomerization of ethylene To a reaction process. |
