1、纳米自组装催化剂对劣质催柴加氢性能的研究李思洋⑴,王鼎聪⑵,赵德智W(1、辽宁石油化工人学石油化工学院,辽宁抚顺113001)(2、中国石化抚顺石油化工研究院,辽宁抚顺113001)摘要:采用二次纳米白组装方法制备堆积密度低、金属负载量高的大孔催化剂。X射线衍射、圧汞和氮吸附等结果表明,共孔径大部分集屮在30nm~100nm,占催化剂孔径分布的44.83%。以劣质催化裂化柴油为原料,在微型反应器中评价纳米口组装催化剂对催化裂化柴油的脱硫、脱氮、芳烧饱和的活性,并用现冇工业催化剂为参比剂(F2)做对比。结果表明,纳米自组装催化剂(FA9)加氢精制劣质催化裂化柴油的最高脱硫、脱氮率
2、达99%,而且有较高的芳绘饱和活性。在反应100h后,催化剂FA9仍然具有较高的活性,其脱硫率、脱氮率、芳绘饱和率分别为95.4%、97.50%、62.41%:而参比剂F2脱硫率、脱氮率、芳绘饱和率分别为94.4%、为98.20%、63.85%。计算结果表明,催化剂FA9的单位体积活性金属的硫脱除率是参比剂F2的1.75倍、氮脱除率是参比剂F2的1.72倍、脱芳饱和率是参比剂F2的1.70倍。关键词:纳米口组装催化剂;催化裂化柴油;脱硫;脱氮;芳烧饱和Theresearchnanoself-assemblycatalystforhydrodesulfurizationofFCC
