Ethylene Oligomerization Over Heterogeneous Catalysts

Ethylene oligomerization has become one of the major research fields of petrochemical industry worldwide aiming at achieving high activity and selectivity to even number atom products. The heterogeneous catalysts prepared from the loading of homogeneous catalysts or transitional metals on supports with proper acidity have demonstrated promising performance in practical applications, among which the nickel loaded heterogeneous catalysts play the dominant role in ethylene oligomerization. This review paper aims to summarize briefly the synthesis, structure, property, and the active sites of the heterogeneous catalysts for the ethylene oligomerization.
