研究了以ＮｉＳＯ＿４／γ－Ａｌ＿２Ｏ＿３为催化剂丙烯齐聚两段反应法制壬烯和十二烯的新工艺。考察了反应温度、空速及溶剂稀释等工艺条件的影响及在第二个反应器前添加丙烯的效果。当两段串联反应器的第一段和第二段的反应温度分别为６０℃和８０℃，反应压力为３．２ＭＰａ，丙烯的液体体积空速（ＬＨＳＶ）为１．５ｈ￣（－１）时，丙烯转化率达９６．５％，壬烯和十二烯的选择性分别为２７．９％（ｗ）和２９．６％（ｗ）。若按二聚物返回反应体系计，目的产物总选择性达８０％。 A new process for the production of nonene and dodecene by oligomerization of propylene over NiSO 4 / γ-Al 2 O 3 catalyst was studied. The effect of process conditions such as reaction temperature, space velocity and solvent dilution, and the effect of adding propylene before the second reactor were investigated. When the reaction temperature was 60 ℃ and 80 ℃, the reaction pressure was 3.2MPa and the liquid hourly space velocity (LHSV) of propylene was 1.5h ~ (-1) in the first and second stages of two series reactors, , The conversion of propylene was 96.5%, the selectivity of nonene and dodecene was 27.9% (w) and 29.6% (w), respectively. If the dimer returned to the reaction system, the total selectivity of the target product of up to 80%.
