precursor used in the preparation of the Pt/AlSBA-15 catalysts. However, the Pt catalyst prepared with AlSBA-15 obtained from aluminium sulphate provided a higher cis-methyldecalins/trans-methyldecalins ratio in the reaction products as compared to the catalysts obtained with aluminium nitrate or aluminium isopropoxide. Consideration was also given to the influence of platinum amount (0.5, 2.5 and 4.5 wt.%)
测试了用各种铝前体获得的含有AlSBA-15的铂催化剂(1.5重量%)在1-甲基萘氢化中的活性。实验是在大气压(240-350°C,W / F = 0.8 g s / cm 3)的连续流系统中进行的。发现在负载Pt的催化剂上的1-甲基萘的转化不受用于制备Pt / AlSBA-15催化剂的铝前体的影响。然而,用由硫酸铝制得的AlSBA-15制备的Pt催化剂提供了更高的顺式-甲基十氢化萘/反式与用硝酸铝或异丙醇铝获得的催化剂相比,反应产物中的-甲基萘烷比率。还考虑了铂含量(0.5、2.5和4.5 wt。%)对双功能Pt / AlSBA-15催化剂(用硫酸铝制得的AlSBA-15)在十氢化萘加氢转化中的催化性能的影响。结果表明,用H 2 PtCl 6浸渍AlSBA-15可以提高布朗斯台德酸度。在具有固定床反应器(5 MPa,300–380°C,H 2:CH = 500 N m 3 / m 3; WHSV
