通过Fe(2 / 3)xNi1-xSO4-P2 O5 /γ -Al2 O3催化剂对 1 -丁烯齐聚反应的催化性能研究 ,考察了催化剂Fe对 (Fe +Ni)的原子分率、焙烧温度、活性组分担载量等催化性能的影响 .结果表明 :Fe0 .5 3Ni0 .2 1SO4复合盐以P2 O5 为助剂的Fe/(Fe+Ni)值为 0 72 ,其担载量为 2 .36mmol/gγ -Al2 O3时催化剂活性最高 .催化剂的最佳活化条件为 4 50℃下非还原气流中活化 4h .The catalyst behavior of Fe (2/3) x Ni 1- x SO 4-P 2O 5/γ-Al 2O 3 in 1-butene oligomerization has been studied. Effects of atomic ratio of Fe/(Fe+Ni), calcination temperature, loading of active constituent and so on were examined. It was found that the atomic ratio Fe/(Fe+Ni) of the catalyst, 0.72, correspondings to the maximum catalytic activity. The catalyst,(2.36 mmol/g) Fe 0.53 Ni 0.21 SO 4-(0.57 mmol/g) P 2O 5 γ-Al 2O 3, was considered to be the best one in 1-butene oligomerization. As the preferable activation conditions, the catalyst calcined in nonreducible atmosphere at 450 ℃ for 4 hours exhibited the best catalytic performance.
