摘要

通过不同钒取代的Keggin型多金属氧酸盐[PMo12-xVxO40](3+x)-（X = 1,2,3,8）（简写为PMoV）与十六烷基三甲基溴化铵[(C16H33)N(CH3)3]（CTAB）反应生成四种固体催化剂CTAB-PMo12-xVx，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-PMo11V1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-PMo11V1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。

Abstract:

Vanadium substituted Keggin-type polyoxometalates [PMo12-xVxO40](3+x)-(X=1, 2, 3, 8) (abbreviated as PMoV) were encapsulated by simple surfactant CTAB forming the surfactant-encapsulated solid catalysts CTAB-PMo12-xVx, which exhibited high activity in oxidation desulfurization. The results showed that CTAB-PMo11V1 could make BT, DBT and its derivatives to be oxidized completely with the conversion of 100% within 6 h. CTAB-PMo11V1 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.
