| 摘 要： | 油品中含硫化合物所产生的危害是多方面的，特别是近年来车用燃料尾气排放的二氧化硫对环境造成的负面影响更引起了人们的关注。发达国家纷纷制定环保法规严格限制油品中硫的质量分数，因此，讨论各种脱硫技术对我国炼油工业具有重要意义。对一种新的脱硫方法进行了考察。将235～270℃之间的煤油馏份进行预先精制，向其中加入一定量的苯并噻吩、二苯并噻吩作为原料，在氮气保护条件下进行烷基化脱硫工艺的研究。实验结果表明：在反应温度为30℃，CH3CH2Br：S=30：1（mol／mol），AgBF4：S=6：1（mol／mol），反应时间为16h的条件下，脱硫率可以达到76．3％。

| Abstract: | Sulfides in oils can lead to harms in many aspects,especially the environment deterioration caused by sulfur dioxide produced from fuel tail gas.The developed countries have made the environment protection regulation to limit the sulfur content in oil products,therefore,it is significant for oil refining industry to discuss various desulfurization technologies.A novel desulfurization process for light oils had been investigated.The mixture consisting of benzothiophene(BT),dibenzothiophene(DBT) and the fract... |
