摘　　要：在超声作用下采用[(C16H31)N(CH3)3]3[PW12040]催化剂将柴油中的含硫有机物(主要为二苯并噻吩类)氧化成相应的砜,用N,N-二甲基甲酰胺(DMF)作萃取剂将砜从柴油中萃取除去。考察了[(C16H31)N(CH3)3]3[PW12040]的量、超声条件(频率、声强)、温度等因素对柴油脱硫的影响。The sulfur-containing organics （such as dibenzothiophene （DBT）） in diesel oil was oxidized to corresponding sulfones by using H202/heteropolyacid quaternary ammonium salt oxidation system under ultrasound, and then the oxidized sulfur compounds were extracted by DMF extractant. The influence of the catalyst dosage, ultrasonic conditions （frequency and intensity）, and reaction temperature on desulfurization of diesel was investigated.
