随着环境法的日益完善,柴油的低硫化成了亟待解决的问题.本文采用浸渍法制备了Cu~(2+)负载型酸化改性Al_2O_3型催化剂,对市售0#柴油进行了等离子体催化氧化脱硫实验研究,后又用自制的新型离子液体(BMIMDBP)对氧化脱硫后的柴油进行萃取脱硫.实验结果表明:在使用板-板式石英反应器,催化剂质量分数为w(catalyst)=5%,空气流速为200 mL/min,放电时间为15min,离子液体与柴油的体积比为1: 1和萃取5次的条件下,脱硫率可以达到52.1%.本方法的实施为柴油脱硫开辟了一条新的途径.

Along with the more and more strict demand on environment protection there was a urgent need to produce low sulfur fuel oil to meet the environmental legistlation.In this paper,acid modified alumina loading copper was prepared by dipping.1-butyl-3- methyl imidazolium dibutylphosphate(BMIMDBP)was prepared and tested in the extraction desulfurization of the 0# diesel oil which was treated with plasma catalytic oxidation.Experimental results showed that with quartz reactor configuration of parallel-board,amount of catalyst was 5% in weight,air flow rate was 200 mL/min,reaction time was 15 min,V_(diesel oil)∶ V_(ionic liquid)=1∶ 1,extracted five times,the desulfurization rate of diesel oil was up to 52.1%.As a result,The new way of desulfurization of dieseloil was founded.
