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。

The two catalysts supported on USY zeolites with surface acid amounts of 626 and 203μmol/g, respectively, showed excellent sulfur tolerance, while the catalysts of higher and lower acid amount showed decreased sulfur tolerance. Energy dispersive spectroscopic analysis proved that the support with a large acid amount adsorbed more sulfur, which might lead to the lower sulfur tolerance of the catalyst.
结果表明硫含量为200μg/g时,载体酸量为626和203μmol/g的两个催化剂的耐硫性最好,而载体酸量更低和更高的催化剂的耐硫性较差,表明载体的酸量太大或太小都不利于催化剂的抗硫性。X射线能量散射分析表明,酸量大时S在酸性位吸附很多,这可能导致催化剂中毒。
