摘　　要：在流化催化裂化(FCC)汽油中加入磷钨杂多酸季铵盐Q_3[PO_4(WO_3)_4](Q=[C_(16)H_(33)NMe_3]^++[C_(18)H_(37)NMe_3]^+)/H_2O_2实现了液—液高效催化氧化降烯烃。研究结果表明:在H_2O_2用量2.5mL、反应时间1h、反应温度60℃、m(汽油):m(催化剂)=40:1、pH值3.3的条件下,FCC汽油中烯烃体积分数降到了23.56%,而汽油辛烷值基本保持不变。The olefin content of FCC（fluid catalytic cracking）gasoline was reduced by a liquid-liquid phase and high efficiency catalytic oxidation system containing heteropolyphosphatotungstate Q3 [-PO4conditions, i. e. , the amount of H2O2 2.5 mL, reaction time 1 h,reaction temperature 60 ℃, the ratio of FCC gasoline and catalyst 40 ： 1 and pH 3.3. The olefin content of FCC gasoline dealt with this system was less than 35%, while the octane number of gasoline did not decrease, which has reached the national standard of clean FCC gasoline.
