Abstract:
The present invention relates to a commercial reaction process for the selective oligomerization reaction of ethylene, and a method for efficiently removing reaction heat to be generated in a reaction and regulating the temperature of the reactor and, more specifically, to an oligomerization reaction process of ethylene by circulating a liquid mixture in the reactor, separating unreacted ethylene from this circulation flow by an apparatus for separating unreacted ethylene from the circulation flow, and then cooling the remaining mixture and reintroducing it to the reactor, thereby removing the reaction heat in the reactor and allowing temperature control.

Claim (Index 9):
The method of  claim 1 , further comprising:\n e) cooling a gaseous layer in the oligomerization reactor of a) and then transferring the cooled gaseous layer to a second fractionation column to be separated into a third gaseous mixture including the unreacted ethylene and the reaction solvent; and a fourth liquid mixture layer including the ethylene oligomer product, a small amount of the reaction solvent and oligomer byproduct; and f) cooling the third gaseous mixture of e) to be circulated to the oligomerization reactor, and transferring the fourth liquid mixture layer to a rear end separation process.
