摘要： 采用磷钨酸和硝酸铜为原料合成磷钨酸铜,以磷钨酸铜为催化剂,H2O2 为氧化剂应用于模拟油氧化脱硫反应。考察了不同的氧化脱硫体系、反应温度、催化剂质量、H2O2 的体积和反应时间对脱硫效果的影响。结果表明,H2O2/磷钨酸铜/十六烷基三甲基溴化铵(CTAB)体系具有最高的脱硫率,当反应的温度为40 曟,催化剂的质量为0.01g,H2O2 加入体积为0.5mL,反应的时间为1h,二苯并噻吩的脱除率为93%,催化剂循环使用5次后,脱硫率没有明显下降。

Abstract: Cpper phosphotungstate was synthesize by phosphotungstic acid and nitric acid copper as raw materials. Oxidative desulfurization reaction of model oil was studied by copper phosphotungstate as catalyst and H2O2 as oxidant. The experiment indicate various oxidative desulfurization system, reaction temperature, catalytic amount, amount of hydrogen peroxide and reaction time influenced on oxidative desulfurization effect. The results show that a combined copper phosphotungstate, CTAB and H2O2 could lead to a good conversion of DBT. Reaction temperature was 40 ℃,catalytic amount was 0.01 g, volume of hydrogen peroxide was 0.5 mL, reaction time was 1 h, which made conversion rate of dibenzothiophene up to 93%. The catalyst may was recycled five times and desulfurization effecience of mode oil isn't decreased. 
