馏分油光化学氧化脱硫的技术进展

The Research on Photooxidative Desulfurization of Petroleum Fractions

由于更加严格的环境法规,柴油超深度脱硫已成为非常紧迫而急需解决的世界性研究课题。为了降低生产成本,各国的研究者正致力于新的深度脱硫方法的研究———非加氢脱硫。在众多的非加氢脱硫中,光化学氧化脱硫因其具有反应条件温和、工艺简单、非临氢操作等特点,成为近年来一个新的研究热点。本文对近年来光化学氧化脱硫的技术进展以及机理等方面的研究加以综述。

The limit of sulfur content of diesel fuel tends to be strict in many countries. So ultra - deep des-ulfurization of fuel oils has become a worldwide environmentally urgent subject due to very stringent environmental regulations. In the non - hydrodesulfurization, photochemical desulfurization is a novel method, which is easy to control and save energy, etc. This paper is a selective review on the photooxidative desulfurization approaches,including mechanism and development.
