轻质燃料油脱硫技术研究进展

Recent process of desulfurization technology of producing clean fuel oil

燃料油中的含硫化合物在燃烧过程中会造成空气污染,形成酸雨。因此,为了改善油品的性能和满足越来越严格的环境保护规格,目前各国都在加紧研究生产清洁燃料的技术对策。作者介绍了清洁燃料的脱硫方法,包括传统的加氢脱硫和非加氢脱硫,如氧化脱硫、吸附脱硫、生物催化脱硫、光催化氧化脱硫、超声波脱硫、络合萃取脱硫、水蒸汽催化等脱硫工艺及其研究进展。

Sulfur in fuel oil is considered a major source of atmospheric pollution because of the formation of acid rain. In order to improve the performances of fuel oil and meet the stricter and stricter legislations of environmental protecting, countries all over the world have been carrying out the new rules of decreasing the sulfur content in fuel oil. This paper reports some methods of desulfurization for the clean fuel and pays more attention to process of desulfurization technology, including hydrodesulfrization and unconventional desulfurization, for example, absorption desulfurition,biocatalytic desulfurition,photocatalysis oxidation desulfurition,ultrasonic desulfurition,complexing--extraction desulfurition,vaporcatalysis desulfurition.
