Abstract: The desulfurization from model and real gasoline by selective adsorption using Cu2(4,4′bipy)2(O3SCH2CH2SO3) was investigated at ambient temperature and pressure. The effect of adsorption time, adsorbent amount and the concentration of 1octene on the adsorption desulfurization performance was studied. The results showed that adsorption rate of model gasoline using Cu2(4,4′bipy)2(O3SCH2CH2SO3) reached 75.6% when the mole ratio of Cu to S was 2, the mass fraction of 1octene in model gasoline was 30% and adsorption time was 120 min. Sulfur content in real hydrotreated gasoline would decrease from 40 μg/g to 8 μg/g after adsorption by Cu2(4,4′bipy)2(O3SCH2CH2SO3), and there was no obvious changes in adsorption performance after recycling 6 times. 

摘要： 以金属骨架材料C u 2( 4, 4 ' - b i p y) 2 - ( O3S CH2CH2S O3) 为吸附剂, 研究了吸附时间、 吸附剂用量和1 - 辛 烯含量等对模拟油脱硫的影响。结果表明, 在常温常压、 C u和S物质的量比为2、 烯烃质量分数为3 0%、 吸附时间 1 2 0m i n下, 脱硫率可达7 5. 6%。在此基础上, 研究了其对加氢后汽油的吸附脱硫效果。结果表明, 吸附剂可以把加 氢后汽油的含硫质量分数从4 0μ g / g降低到8μ g / g; 再生后的吸附剂重复使用6次, 其性能基本不变。
