Investigation of Propene Oligomerization Catalyst Series Derived from Complex of Ferric Sulfate and Nickel Sulfate

Some paper have reported that catalyt of NiSO₄/γAlO₃ has a very high oligomerization activity for propene, but the over tri oligomerization selectivity is very low^[1].The catalyt of Fe₂(SO₄)₃/γ-Al₂O₃ has a very high over trioligomerization selectivity, but oligomerization activity was lower then catalysis of NiSO₄/γ-Al₂O₃ for propene and stability of catalysis was not as good as catalysis of NiSO₄/γ-Al₂O₃^[2].In this paper the catalysis of Fe_(2/3)xNi_1-xSO₄-P₂O₅/γ-Al₂O₃ for propene oligomerization has been systematically studied, the effect of the activation method, the stability and reaction conditions on activity and selectivity were investigated. Fe_(2/3)xNi_1-xSO₄-P₂O₅/γ-Al₂O₃ catalysis was preparared by impregnation.The factors affecting catalyst performance for propene oligomerization are as follows.
