摘　　要：考察了以H2O2为氧化剂,对催化柴油进行氧化脱硫。讨论了实验方法、催化剂及用量、破乳剂、氧化剂用量和萃取剂及用量等因素对反应的影响。实验结果表明,当选用一步法氧化萃取工艺,C6为催化剂,其用量为5%(质量比),破乳剂NP6的用量为4%(体积比),氧化剂H2O2的用量为10(氧硫物质的量比),萃取剂按B∶D=1∶1组成,萃取剂油比为1时,得脱硫率为46.90%,收率为99.50%。The oxidative desulfurization of catalytic diesel with using H2O2 as oxidant is studied. The effects of experimental method, catalysts and its dosage, demulsifier, amount of oxidant and extracting agent and its dosage on the reaction are discussed. The results show that the desulfurization rate is up to 46.90% and the yield is 99.50% when the one-step extracting process is adopted, and using C6 as catalyst which mass ratio is 5%, the amount of demulsifier NP6 is 4%, the amount of oxidant is 10（ratio of oxygen to sulfur）, the extracting agent composition is B and D （the ratio is 1：1）, and the volume ratio of extracting agent to oil is 1：50.
