Ethylene oligomerization catalyst and use thereof |
摘要 |
Ethylene is oligomerized with a catalyst in which nickel is supported on a support containing silica and alumina. The catalyst has little deterioration over long periods and affords oligomers with high productivity. The ethylene oligomerization catalyst includes a support and a nickel compound supported on the support, the support including silica and alumina, and the amount of nickel supported is in the range of 0.0001 to 1 wt % based on the weight of the support, and the molar ratio of silica to alumina in the support (SiO2/Al2O3) is in the range of 100 to 2000. In a process of the invention, ethylene is oligomerized with use of the catalyst. |
