During the design of fixed bed adsorbers, it is vital to understand thedynamic adsorption properties of the system. Because temperature is one of themost important factors affecting adsorbent performance, such that the dynamicadsorption coefficients tend to increase as the temperature decreases, thedynamic adsorption characteristics of Xe on a fixed bed adsorber at 77 K werestudied in the present work to minimize the volume of fixed bed adsorber,employing a variety of adsorbents under different operational conditions. Theresults show that the adsorption performance of carbon molecular sieve issuperior to that of activated carbon. And both operational conditions and thepresence of gaseous impurities were found to affect adsorption properties.
