摘要

去除硫化物和芳香族化合物以生产清洁燃料的过程,是对减缓和适应气候变化进程的一项重要而有效的贡献。相比之下,有必要找到一种创新的方法来去除硫和致癌芳香族化合物,因为目前世界各国普遍使用清洁的低硫柴油。因此,在这项工作中,我们研究了使用甲醇、乙腈和乙酰乙酸乙酯等多种有机溶剂作为萃取剂时,微波辐射功率和辐照时间对去除硫含量为 450 ppm、芳烃含量为 16 wt%的实际柴油进料中的硫和芳烃化合物的影响。结果表明,这项工作中使用的最佳溶剂是乙酰乙酸乙酯。结果表明,在以下理想条件下,微波辅助萃取脱硫技术实现了较高的脱硫率(≈ 92%):辐照时间为 7 分钟,溶剂进料比为 3:1,微波强度为 180 W。为了揭示不同有机溶剂微波辅助萃取脱硫的机理,还对二苯并噻吩(DBT)或二甲基二苯并噻吩(DMDBT)与不同有机溶剂之间的相互作用进行了理论研究,包括结构检测和相互作用能分析。

The role of microwave radiation in extractive desulfurization of real diesel fuel for green environment: an experimental and computational investigation

The process of removing sulfur compounds and aromatic compounds to produce clean fuel is an important and effective contribution to the processes of mitigating and adapting to climate change. In contrast, it is necessary to find an innovative way to remove sulfur and carcinogenic aromatic compounds because clean, low-sulfur diesel is commonly used in all countries of the world at the present time. Therefore, in this work, we have studied the effect of the microwave radiation power and the irradiation time with the use of more than one type of organic solvent; methanol, acetonitrile and ethyl acetoacetate; as an extractant and solvent to feed ratio impact on the removal of sulfur and aromatic compounds of a real diesel fuel feed which has 450 ppm sulfur content and 16 wt% aromatic Content. The results showed that the best solvent used during this work was ethyl acetoacetate. According to the results, high sulfur removal (≈ 92%) was accomplished with microwave-assisted extractive desulfurization technique under the following ideal conditions: the irradiation time is 7 min, the solvent feed ratio is 3:1 and the microwave intensity is 180 W. To reveal the mechanism of microwave-assisted extractive desulfurization via different organic solvents, a theoretical study including structural examination and interaction energy analysis on the interaction between dibenzothiophene (DBT) or dimethyl dibenzothiophene (DMDBT) and the different organic solvents was also conducted.

期刊介绍: BMC Chemistry, formerly known as Chemistry Central Journal, is now part of the BMC series journals family. Chemistry Central Journal has served the chemistry community as a trusted open access resource for more than 10 years – and we are delighted to announce the next step on its journey. In January 2019 the journal has been renamed BMC Chemistry and now strengthens the BMC series footprint in the physical sciences by publishing quality articles and by pushing the boundaries of open chemistry.
