Test and Development of a Regenerative CO
Removal System for Possible Use in the Apollo Applications Program
The paper reports basic adsorption data for CO2 and water vapor on molecular sieves and silica gel, a mathematical model used to predict the behavior of regenerative adsorption multibed systems, and prototype tests of an Apollo size system and comparison of this system with model predictions. The basic data include equilibrium isotherm data and non-equilibrium adsorption and desorption data taken in a small cross-section bed. The prototype tests were performed in a 6 by 6 by 6 in. adsorption bed that was packed with silica gel and molecular sieve.
