At present, diesel oil plays a more and more important role in the various kinds of fuel. But compare to gasoline, diesel oil has a high rate of sulfur compound. The sulfur compound is existed mainly as thiphene and thiphene ramification. These kinds of sulfur compounds are not easy to remove by adding hydrogenation. Thats why diesel oil has a high rate of sulfur compound. So it makes profound desulfurization a hot topic and a difficult problem in and outside the country. This paper takes dibenzonthiophene as a model to study the profound desulfurization of diesel oil with the help of biology and the oxygenating desulfurization under the condition of ultrasonic and microwave.

目前，柴油在燃料油中占的比重越来越大，而柴油较汽油馏分重，其硫化物主要以噻吩及噻吩衍生物的形式存在，这类硫化物用加氢的方法难以脱除，使柴油的含硫量较高，因此柴油的深度脱硫是国内外研究的热点和难点，本文以二苯并噻吩作为模型化合物，考察微生物的协同条件下对柴油的深度脱硫，超声波条件和微波条件下的氧化脱硫，并对超声波条件和微波条件下柴油的深度脱硫进行了对比。
