以过氧化氢为氧化剂，磷钨酸为催化剂，四乙基溴化铵为相转移催化剂，糠醛为萃取剂，采用催化氧化反应与溶剂萃取相结合的试验方法对焦化柴油进行硫氮脱除反应，并对工艺条件进行优化。结果表明，以50 mL焦化柴油为基础，在H2O2体积为7 mL、磷钨酸用量为0.28 g/L、四乙基溴化铵质量为0.10 g、反应温度60℃、氧化反应70 min、25 mL糠醛萃取三次的最优工艺条件下，柴油中硫质量分数由647μg/g降至62.58μg/g，脱硫率达90.33%；而氮质量分数由775.26μg/g降至29.85μg/g，脱氮率高达96.15%。氧化溶液与萃取剂回收后经处理均可重复利用。

Taking hydrogen peroxide as oxidant, phosphotungstic acid as catalyst, tetraethyl-ammonium bromide as phase transfer catalyst, furfural as extraction agent, desulphurization and denitrification of the coking diesel were carried out by using combined process of catalytic oxidation reaction and solvent extraction, and the process conditions were optimized. The results show that ,under the optimal process conditions of hydrogen peroxide 7 mL , phosphotungstic acid 0.28 g/L,tetraethyl-ammonium bromide 0.10 g,reaction temperature 60℃,reaction time 70 min,furfural extraction three times based on the 50 mL coking diesel, the desulfurization rate is as high as 90.33%and the sulphur content decreases from 647 μg/g to 62.58 μg/g;the denitrification rate is as high as 96.15% and the nitrogen content decreases from 775.26μg/g to 29.85μg/g. The oxidation solution and extraction agent can be reused after processing.
