Future Recovered Gas Dryer Development

Abstract

Building on our successful development of a water detritiation process, this project was extended to ammonia detritiation using a catalytic isotope exchange process with hydrogen (H 2 ) for the next generation of RGD materials. In these processes, isotopic exchange between flowing H 2 with adsorbed tritiated species is facilitated by trace amounts of an active catalyst component (e.g. Pt) that is loaded onto a zeolite. Since the catalyst loading may alter the zeolite pore size, Pt/zeolite performance for moisture and ammonia adsorption underwent verification in addition to characterization of the remediation process. The performance was evaluated for catalytic isotope exchange of deuterated water and deuterated ammonia (surrogates) with H 2 at ambient temperatures.
