A STUDY OF VACUUM CRYOSORPTION BY ACTIVATED CHARCOAL

Abstract

An experimental program was carried out in the 10 to the -8 to 10 to the -2 power torr region to supply basic information on the adsorption of noncondensable gases at 77 K and to establish the functional dependence of adsorption rate on pressure and amount of gas adsorbed. From the experimental results, analytical expressions are developed which describe the behavior of adsorption rate in terms of the adsorption parameters for high vacuum, low temperature conditions. These expressions are shown to agree with the observed pressure-time variations resulting from charcoal adsorption provided the charcoal remains well below saturation.
