Problems solved by technology

However, the cooling coil and the heating coil coexist on the surface of the reactor, and the reaction mixture in the reactor directly contacts the surface of the cooling coil and the heating coil, which has certain limitations in solving the problem of a sharp drop and rise in the temperature of a part of the reaction mixture.

Abstract

The present invention relates to a commercial reaction process for a selective oligomerization reaction of ethylene, and to a method for efficiently removing reaction heat to be generated in the reaction and regulating the temperature of the reactor and, more specifically, to an oligomerization reaction process of ethylene, wherein a liquid mixture is circulated within the reactor, through a device for separating unreacted ethylene in a circulation flow to be generated, separates the unreacted ethylene in the circulation flow, and cools remaining mixture to be re-entered, thereby being capableof removing the reaction heat and regulating the temperature.

Description

technical field [0001] The invention relates to an industrialized reaction process for selective oligomerization of ethylene and a method for effectively removing reaction heat generated in the reaction and adjusting the temperature of a reactor. More particularly, it relates to a process for the oligomerization of ethylene by recycling the liquid mixture in the reactor, separating unreacted ethylene from a recycle stream by means of means for separating unreacted ethylene from the recycle stream, and The remaining mixture is then cooled and reintroduced into the reactor, thereby removing the heat of reaction within the reactor and allowing temperature control. Background technique [0002] The process technology for preparing oligomers from ethylene is very useful in industry. Among the α-olefins produced by the process of producing oligomers from ethylene, the α-olefins with high market value are 1-hexene and 1-octene. The 1-hexene and 1-octene are important industrial...
