摘要 以改性Y分子筛和氧化铝为载体、Ni-W为活性组分,采用等体积浸渍法制备催化剂,在不同的温度下进行热处理,通过XPS、HRTEM、SEM-EDS等分析方法对其进行表征,考察了热处理条件对加氢裂化催化剂性能的影响。结果表明,当催化剂热处理温度为500℃时,活性组分的硫化度达到最大值,在载体表面均匀分布。同时,WS2片晶层数较高,片晶长度较短,产生更多的加氢活性位。热处理温度在500℃时,催化剂的裂化性能达到最佳状态。

Abstract: With modified Y molecular sieve and alumina as supports,Ni-W as active component,the catalysts are prepared by the incipient wetness impregnation method,and then thermally treated at different temperatures.The influence of thermal treatment conditions on the performance of the catalysts for hydrocracking are investigated by XPS,HRTEM,EDS analysis and other characterization methods.The results show that the active components in the catalysts get the maximum vulcanization degree,and distribute uniformly on the surface of the support when the catalyst has been thermally treated at 500℃.At the same time,WS2 lamellar crystals in the catalyst has higher layer number and shorter average length,and generates more hydrogenation active sites.It is revealed that the catalyst that has been thermally treated at 500℃ delivers the best performance for hydrocracking.
