Method for inhibiting formation of polyethylene wax in ethylene oligomerization reaction |
| abstract |
The invention discloses a method for inhibiting the formation of polyethylene wax in the ethylene oligomerization reaction, which comprises: premixing or separately adding a cocatalyst, a main catalyst and a polyethylene wax inhibitor to an oligomerization reactor containing a reaction medium, and controlling At a suitable reaction temperature, ethylene monomer is introduced to the reaction pressure, and ethylene oligomerization is carried out to prepare a higher linear alpha-olefin. The polyethylene wax inhibitor is selected from one or more of the group of aromatic amine compounds (Ar-NH 2 ). The invention can effectively inhibit the production of the polyethylene wax and improve the production of the liquid phase α-olefin, thereby greatly reducing the content of the polyethylene wax in the ethylene oligomerization reaction product, and is beneficial to the safe and stable operation of the device to obtain a high economy. benefit. |
