| titleOfInvention | Three-way catalyst system and application thereof in ethylene oligomerization reaction |
| abstract | The invention provides a three-way catalyst system and an application thereof in ethylene oligomerization reaction, wherein the three-way catalyst system is obtained by complexing raw materials which mainly comprise phosphine-nitrogen ligand shown as a structure in a formula I, a metal precursor taking chromium as a center and a cocatalyst; the molar ratio of the metal precursor, the phosphine-nitrogen ligand shown in the structure of the formula I and the cocatalyst is 1: 0.1-10: 1-1000, preferably 1: 1-1.6: 400-600; the ternary catalyst system obtained by the method is applied to the ethylene oligomerization reaction, the selectivity of alpha-olefin in the ethylene oligomerization reaction process is improved, and the sum of the selectivity of 1-hexene and 1-octene in the oligomerization reaction reaches more than 82 percent |
