Abstract

Adsorption of CO₂, N₂, CH₄ and H ₂ on triaminegrafted pore-expanded MCM-41 mesoporous silica (TRIPE- MCM-41) was investigated at room temperature in a wide range of pressure (up to 25 bar) using gravimetric measurements. The material was found to exhibit high affinity toward CO₂ in comparison to the other species over the whole range of pressure. Column-breakthrough dynamic measurements of CO ₂-containing mixtures showed very high selectivity toward CO ₂ over N₂, CH₄ and H₂ at CO ₂ concentrations within the range of 5 to 50%. These conditions are suitable for effective removal of CO₂ at room temperature from syngas, flue gas and biogas using temperature swing (TS) or temperature-pressure swing (TPS) regeneration mode. Moreover, TRI-PE-MCM-41 was found to be highly stable over hundreds of adsorption-desorption cycles using TPS as regeneration mode.
