| 摘 要： | 采用浸渍法和混捏法对FCC汽油选择性加氢脱硫催化剂载体进行改性，研究结果表明，浸渍法改性仅能使催化剂的加氢脱硫选择性略有提高；混捏法改性可使载体的酸性显著下降，同时比表面积和平均孔径也有不同程度的降低，有利于提高催化剂的加氢脱硫选择性，当载体中碱性组分Mb含量为（x＋40）％时，催化剂具有最佳的加氢脱硫选择性。10天的稳定性试验结果表明，改性载体所制备的催化剂具有良好的稳定性。 |

| Abstract: | The support of selective hydrodesulfurization(HDS)catalyst for hydrotreating FCC naphtha was modified by impregnation or kneading methods.It was found that impregnating alkali metal had no significant effect on the catalyst HDS selectivity.Kneading could reduce the support acidity obviously,and the surface area and average pore radius of the support were decreased in some extent,which were beneficial for improving catalyst HDS selectivity and reducing olefin saturation rate.The optimal catalyst HDS selectivity was observed at a basic component(Mb)content of(x+40)%.A 10-day continued running results showed that the catalyst had good stability with HDS rate over 80% and olefin saturation rate about 20%. |
