In previous studies, purification based on the adsorption principle has been proved to have low separation cost, and the selection of an adsorbent is a crucial factor in this method. To enhance H2S sorption capacity, an ordered SBA-15 silica mesoporous material with a high specific surface area is synthesized as a carrier of triethanolamine (TEA). The mesoporous molecular sieve SBA-15 coated with a TEA film considerably enhances H2S sorption capacity. The effects of operational variables on H2S removal efficiency, including the amount of TEA-loading, adsorption pressure, flow rate, and fixed bed length, are investigated with a single-column adsorption apparatus. A model demonstrating H2S dynamic sorption processes through as TEA-modified adsorbent bed is proposed. The model fits well the experimental data and can be applied to the H2S sorption process simulation and optimal process design.
