利用浸渍法制得镍负载硅酸铝催化剂(Ni-SA),在小型固定床高压反应装置上评定了催化剂的活性,考察了催化剂活化条件和反应条件对催化性能的影响.结果发现,在最佳条件下,Ni-SA 催化剂用于丙烯齐聚反应转化率可选90%以上,三聚和四聚选择性总和达70%左右,催化剂寿命达630L 产品油/kg 催化剂.可见催化剂是一种具有工业应用前景的良好丙烯三、四聚催化剂.
The nickel-supported aluminum silicate catalyst (Ni-SA) was prepared by impregnation method and the activity of the catalyst was evaluated on a small fixed-bed high pressure reactor. The effects of catalyst activation conditions and reaction conditions on the catalytic performance were investigated. Ni-SA catalyst for oligomerization of propylene oligomerization reaction rate of more than 90% optional, trimerisation and tetramerization selectivity of about 70%, the catalyst life of 630L product oil / kg catalyst shows that the catalyst is a catalyst with Good industrial application of propylene three, four polymerization catalyst.
