Abstract
The present invention relates to a method and an apparatus for producing an α-olefin low polymer by subjecting an α-olefin to low polymerization reaction in the presence of a catalyst in a liquid phase part within a reactor, and the present invention relates to a method and an apparatus for producing an α-olefin low polymer, such as 1-hexene, etc., by subjecting an α-olefin, such as ethylene, etc., to low polymerization reaction, in which the formation of a polymer on an upper tube plate surface of a shell and tube type heat exchanger that is used for heat removal is suppressed, thereby performing a continuous operation stably over a long period of time.
