METHOD FOR PRODUCING Α-OLEFIN OLIGOMER

Номер: WO2016047560A1
Автор: EMOTO Hiroki
Принадлежит:

The present invention relates to: a method for producing an α-olefin oligomer by performing an oligomerization reaction of an α-olefin in a reaction solvent within a reactor in the presence of a catalyst, wherein a non-concentrated gas and a condensate liquid obtained from an outlet port of a heat exchanger by introducing some of a gas in the gas phase part within the reactor into the heat exchanger and cooling the gas in the heat exchanger are circulated and supplied to the reactor, and wherein the temperature of the liquid phase part within the reactor is from 110°C to 150°C and the outlet temperature of the heat exchanger is from 50°C to 100°C; and an apparatus for producing an α-olefin oligomer.

METHOD FOR PRODUCING α-OLEFIN OLIGOMER

Номер: WO2011118533A1
Автор: TODA Satoshi, EMOTO Hiroki, YOKOYAMA Kazuyuki
Принадлежит:

Disclosed is a method for producing an α-olefin oligomer by an oligomerization reaction of α-olefin, which has a higher catalytic activity and a higher product selectivity and can suppress the formation of a polymer which is a by-product causing process blocking, and therefore is industrially advantageous. The method for producing an α-olefin oligomer comprises performing an oligomerization reaction of α-olefin, which is a starting material, in a solvent in the presence of a catalyst, thereby obtaining an α-olefin oligomer, which is a reaction product. The catalyst contains a transition metal-containing compound, an aluminum-containing compound, and a halogen-containing compound. The content of water in the solvent in a reactor is from 0.1 to 13.0 ppm by weight.

PRODUCTION METHOD FOR α-OLEFIN OLIGOMER

Номер: WO2016158621A1
Автор: EMOTO Hiroki
Принадлежит:

The purpose of the present invention is to provide a method for efficiently producing an α-olefin oligomer having suppressed aging deterioration of catalytic activity, high α-olefin oligomer selectivity, and a high α-olefin oligomer yield. The present invention pertains to a method whereby: an α-olefin oligomerization reaction using a catalyst including a chlorine atom-containing compound (d) is performed, in the presence of a reaction solvent; and an α-olefin oligomer is obtained. The production method provides a prescribed ratio of the chlorine atom-containing compound (d), being at least two types of compound having a specified chlorine atom separation speed.

METHOD FOR PREPARING α－OLEFIN OLIGOMER

Номер: WO2016152591A1
Автор: EMOTO Hiroki
Принадлежит:

The present invention addresses the problem of providing a method for suppressing the precipitation of a highly concentrated polymer dissolved in a solvent in an operation suspending step, and for suppressing device blockage due to the polymer even when the highly concentrated polymer is precipitated. The present invention pertains to a method for preparing an α－olefin oligomer, the method comprising a production operating step and an operation suspending step, wherein the feed position of a feed solution to a distillation column in the operation suspending step is set lower than the feed position of the feed solution to the distillation column in the production operating step.
