摘　　要：通过不同钒取代的Keggin型多金属氧酸盐[PMo_(12-x)V_(x)O_(40)]^((3+x)-)(X=1,2,3,8)(简写为PMoV)与十六烷基三甲基溴化铵[(C_(16)H_(33))N(CH_(3))_(3)](CTAB)反应生成四种固体催化剂CTAB-PMo_(12-x)V_(x),比较了四种复合物的催化氧化脱硫性能。实验结果表明催化剂CTAB-PMo_(11)V_(1)的脱硫效果最佳,在6小时内能将模拟油中500ppm的BT、DBT及其衍生物完全转化。对CTAB-PMo_(11)V_(1)进行了FT-IR、XRD和SEM等表征。另外,对影响催化剂氧化脱硫效率的各种因素、催化剂的稳定性及反应机理也进行了探讨。Vanadium substituted Keggin-type polyoxometalates[PMo_(12-x)V_(x)O_(40)]^((3+x)-)(X=1,2,3,8)(abbreviated as PMoV)were encapsulated by simple surfactant CTAB forming the surfactant-encapsulated solid catalysts CTAB-PMo_(12-x)V_(x),which exhibited high activity in oxidation desulfurization.The results showed that CTAB-PMo_(11)V_(1)could make BT,DBT and its derivatives to be oxidized completely with the conversion of 100%within 6 h.CTAB-PMo_(11)V_(1)was characterized by IR、XRD and SEM analysis.In addition,various factors affecting the oxidation desulfurization process,the stability of the catalyst and the reaction mechanism were discussed in the model oil.
