摘要
Abstract
Mesoporous materials SBA-15 modified by different transition metals,including Zn、Fe、Mn、Cu、Co and Ni,were synthesized by impregnation method respectively.The prepared materials were characterized by XRD and BET.Among these six adsorbents,Zn/SBA-15 showed the highest H2S breakthrough capacity of 29.7 mg？g-1adsorbent with 23 wt% loading of zinc.The effect of the gas flow rate,adsorption temperature,the affects of the exit of carbon dioxide and oxygen were also investigated.Zn/SBA-15 could be recycled for four times at 573 K in air environment,and its breakthrough capacity remained same.关键词
