| 摘 要： | 为了满足未来更为严格的含硫尾气的排放标准，燃料油的深度脱硫是当今国内外非常活跃的研究领域．由于过氧化氢氧化脱硫法具有较高的脱硫效率，同时，二次污染小，因此，有关H2O2选择性催化氧化与萃取相结合的方法成为倍受关注的方法之一．综述了国内外近几年关于H2O2氧化脱除燃料油中的含硫杂环化合物的研究进展．根据H2O2和催化反应体系的相态可分为两相催化体系和多相催化体系，详细介绍了这两种方法．最后提出目前过氧化氢氧化脱硫法存在的主要问题是过氧化氢使用效率较低和催化剂的回收及再利用．

| Abstract: | Ultra -deep desulfurization of fuel oils has become an environmentally urgent subject worldwide to meet the new emission control standards. Selective catalytic oxidation combined with extraction is one of the most promising ultra - deep desulfurization methods using H2O2 as oxidant owing to the high efficiency of H2O2 and the low pollution. Study on H2O2 oxidative desuffurization of fuel oil was reviewed in recent years. Biphasic catalysis system and heterogeneous catalysis system were introduced in detail according to the phase state between the H2O2 and catalytic system in this paper. At present, the main obstacles to the industrial application of the process are the low - oxidation activity of H2O2 and the difficulties in separation and recovery of the catalysts after reactions. |
