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 H2S 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.
