Abstract
The trace contaminant control system (TCCS) utilizes packed beds of Barnebey-Sutcliffe (B-S) Type 3032 to remove ammonia from ISS cabin air. BS Type 3032, an acid-impregnated activated carbon, is no longer produced and must be replaced. The adsorptive capacities of Calgon Carbon Ammonasorb II and Molecular Products Chemsorb® 1425 for ammonia were measured using moist (40% RH) spacecraft simulated gas streams. These candidate replace-ment sorbents had 66% greater ammonia removal capacities at low (5 ppm) ammonia con-centrations than B-S Type 3032.
