摘要:实验中合成了反应控制型泡沫催化剂和常规多聚钼酸盐催化剂,并对催化剂进行了元素分析、FT-IR、
UV-DRS、NMR 和 TG-DSC 表征。以二苯并噻吩(DBT)为模型化合物,考察了催化剂的催化氧化脱硫效果。
同时考察了不同反应条件对反应控制型泡沫催化剂[C16mim]2Mo2O3(O2)4·H2O 脱硫率的影响,并考察了
[C16mim]2Mo2O3(O2)4·H2O 对不同硫化物脱除的效果。实验表明,最佳反应条件为 n(S) : n(催化剂) : n(H2O2)
= 30:1:180,T=50℃。在最优条件下,[C16mim]2Mo2O3(O2)4·H2O 对 DBT 脱除率可达 %,达到深度脱硫效果;
四种不同芳香烃类硫化物的催化活性按 R-SH > DBT > 4, 6-DMDBT > BT 依次降低。该体系可以循环 8 次,
活性没有显著降低。

Abstract: In this paper, a reaction-controlled foam-type catalyst and conventional poly-molybdate
catalyst were synthesized and characterized using elemental analysis, FT-IR, UV-DRS, NMR and
TG-DSC. [C16mim]2Mo2O3(O2)4·H2O was taken as the catalyst to investigate the best reaction
condition by a series of experiments. The suitable condition is: n(S) : n(catalyst) : n(H2O2) =
30:1:180, reaction temperature 50℃. The oxidation reactivity of different substrates was as
following: R-SH > DBT > 4, 6-DMDBT > BT. The catalytic system could be recycled for eight
times without significant decrease in catalytic activit
