Abstract
It is well known that the support of sorbents plays a crucial role in gas diffusion and sulfidation reaction, and the supports of big specific areas and large pore volumes are beneficial for H2S adsorption [1]. Mesoporous carbon aerogel, a 3-D network structure of interconnected nanosized primary particles, is regarded to be a preferable support. Carbon aerogels have a unique porous structure, including well-developed and controlled interparticle mesopores and intraparticle micropores, huge pore volume, and large specific surface area. Additionally, the carbon aerogels remain stable under high temperature , and they could be formed into various shapes and can be used without any further forming treatment, which makes these materials attractive as the support of the desulfurizer [2,3,4].
