Abstract:

A test program was conducted to study low temperature adsorption of carbon dioxide by synthetic zeolites for possible application to space vehicle environmental control systems. Type 5A molecular sieves and a 1 mole per cent carbon dioxide concentration were used for most of the tests. The range of test conditions included temperatures from 530 to 300 R, and process air superficial velocities from 30 fpm to 150 fpm. Presented in the report are the results of the tests which include 1 the effect of superficial velocity on adsorption, 2 the effect of bed length on adsorption, 3 the effect of low temperature on adsorption, 4 vacuum and thermal desorption of sieve adsorbed at low temperatures, and 5 miscellaneous data, such as pressure drop, temperature rise, and pellet size. The experimental results are extensively presented and include adsorption curves showing sieve load as a function of time, as well as curves of sieve capacity and adsorption efficiency.
