摘要：炭基材料因其发达的孔隙结构和丰富的官能团而被广泛用于H2S的干法脱除，基于其在脱硫过程中所起作用的不同可分为两大类：一类是利用炭基材料本身的物化特性直接作为吸附剂脱除H,S；另一类是炭基材料作为载体负载金属氧化物制备成吸附剂，利用金属组分与硫的作用脱除H2S。本文详细综述了炭基材料干法脱除 H2S的研究进展，具体分析了不同类型炭基吸附剂脱除HS时的温度、气氛等条件对其脱硫行为的影响以及改性活化方法和制备工艺与其脱硫能力间的关系。由于炭基材料干法脱除HS的过程相对湿法脱除省云换热过程，
且炭基材料廉价易得，有很高的脱硫率，所以其比传统的脱硫工艺更具优势和研究前景。关键词：炭基材料；干法脱硫；硫化氢；吸附剂；活化

Abstract: With the advantages of the well developed pore structures and the abundant functional groups, carbon-based materials are widely used in dry desulfurization process. According to various reactions in desulfurization process, sorbents from carbon-based materials are mainly classified into two types. One is used to adsorb H2S directly as a sorbent. The other is used as the support for loading active components,by which HzS is removed by the interaction between metal active components and sulphur. The research progress in dry desulfurization was reviewed in detail in this article. In order to illustrate the process concretely, the effects of temperature and atmosphere on desulfurization behaviors have been analyzed. The relationship of its desulfurization capacity with the modified activation methods and the preparation conditions of carbon-based materials sorbent were also investigated. Compared with wet desulfurization, the carbon-based materials in dry desulfurization method is attractive by its cheap price, availability,high-desulfurization rate, and no heat transfer process needed. Thus the method has more merits and broad research prospect than the traditional desulfurization.
