活性炭用于柴油深度脱硫研究进展

综述了活性炭作为吸附剂和催化剂在柴油深度脱硫方面应用的新进展。通过表面热氧化和负载金属离子对活性炭表面进行化学性能改性，有效提高对柴油中噻吩类硫化物的吸附性能。活性炭作为催化剂，能有效催化过氧化氢和氧化柴油中的噻吩类硫化物而达到催化氧化脱硫。活性炭在柴油深度脱硫方面具有广阔的应用前景，但要真正实现其在脱硫上的工业化应用，尚需加强其表面化学性能改性、再生、吸附和催化氧化机理等方面的研究。

Advances in deep desulfurization of diesel by activated carbon

The advances in activated carbon as adsorbent or catalyst used for deep desulfurization of diesel were reviewed. The adsorption capacity of thiophenic sulfur compounds on activated carbon was increased efficiently by thermal oxidation and loading metal ions methods. And thiophenic sulfur compounds of diesel were removed by oxidation with hydrogen peroxide on activated carbon as catalyst. The research of modification for activated carbon surface, regeneration, adsorption and mechanism of catalytic oxidation will be enhanced. Activated carbon used in deep desulfurization of diesel has wide application prospect.
