Syracuse University proposes to develop an understanding of the different mechanisms of silver-aging processes on adsorbents exposed to off-gas streams to enable prediction of long-term operation of gas treatment systems. Experiments to be conducted on silver-exchanged mordenite (Ag0Z) and silver-functionalized silica aerogel (Ag0-aerogel) include aging effects of dry air, humid air, and dry air containing 2v/v% NO2 or 1v/v% NO over periods of 1, 2, 4, and 6 months. Data obtained will be used to develop models for sorbent deactivation, which will be employed in our models of multicomponent adsorption equilibria and adsorption kinetics that include aging affects to predict column adsorption.
