CATALYTIC BEHAVIOR OF NiSO4/γ-Al2O3 FOR PROPENE OLIGOMERIZATION
Abstract:
The catalytic activity of NiSO4/γ-Al2O3 in propene oligomerization is greatly influenced by the acidity of the catalyst used. It was found that the acid sites related to propene oligomerization are only those of H0≤-3.0. The generation of Ni+ and its role as an active site in the oligomerization were demonstrated by the electronspin resonance method (ESR) and CO poisoning. The oligomerization is believed to be proceeded by coordination catalysis over Ni+ as well as acid catalysis over the acid sites of the supported catalyst.
