柴油氧化脱硫技术研究进展

Progress on desulfurization of diesel fuel

介绍了近年来柴油氧化脱硫技术研究的进展情况,主要包括:H2O2均相、非均相催化氧化脱硫,超声波氧化脱硫,光催化氧化脱硫和分子氧直接氧化脱硫等。认为分子氧直接氧化脱硫技术克服了H2O2价格较高、稳定性差等缺点,并且该法具有操作条件缓和,反应时间短等优点,将成为柴油氧化脱硫的主要研究方向。

New desulfurization technologies have been developed in recent years to reduce the sulfur content in diesel fuel. Oxidative desulfitrization （ODS） is considered to be one of the promising methods for super deep desulfurization of diesel fuel. The latest progress of ODS of diesel fuel is reviewed. The ODS researches include homogeneous and heterogeneous catalytic oxidation using H2O2 and O2, oxidation assisted by ultrasound and photocatalytic oxidation. Oxidative desulfurization with air can be carried out under very mild conditions and in a shorter time. Moreover, it avoids the shortcoming of high cost and poor stability of H2O2. Therefore, oxidative desulfurization with air will become an important study area for oxidative desulfurization of diesel fuel.
