Condensed case for TRI-PE-MCM-41: "Adsorption of CO2 on triamine-grafted pore-expanded mesoporous silica, TRI-PE-MCM-41, was investigated from very low pressure to 1 bar at four temperatures (298, 308, 318, 328 K[elvin]) using gravimetric measurements. TRI-PE-MCM-41 exhibited one of the highest equilibrium capacities compared to other typical CO2 adsorbents such as zeolites, activated carbons, and metal-organic frameworks (MOFs). In contrast, under the same pressure and temperature conditions, TRI-PE-MCM-41 exhibited very small uptakes of N2, CH4, H2, and O2. Column-breakthrough measurements of CO2 in mixtures with other species showed exceedingly high selectivity of CO2 over N2, CH4, H2, and O2 even at very low CO2 concentrations, indicating that TRI-PE-MCM-41 is suitable adsorbent for gas purification applications. Moreover, water vapor was found to have a beneficial effect on CO2 adsorption capacity even at very low CO2 partial pressure, e.g. 400 ppm, without adverse effect on CO2 selectivity."

Dr. Sayari et al. advances a compelling case for patented adsorbent TRI-PE-MCM-41 (exclusively licensed to CSMG) in the above abstract. Lucid, persuasive prose to boot. Along with two other solid sorbents selected from over one-hundred candidates, TRI-PE-MCM-41 has been handed off to ADA Environmental Solutions (ADES) for field testing at a coal-fired utility plant, the test sponsored by a DOE grant. On 14 May 2010, ADA-ES mentioned that results of "initial field tests" are pleasingly consistent with "promising" experimental (lab) results. That would seem to bode very well for CSMG because Sayari's TRI-PE-MCM-41 has performed splendidly in the lab. In that vein, Sayari et al. have recently published a study comparing experimental results with theoretical model values; the lab results are in "close agreement".
