✦ Synopsis

An experimental study, of selective adsorption of very low level carbon dioxide impurities (in oxygen) on a Linde type 13X molecular sieve, has been described. The adsorption process was studied dynamically using laboratory scale apparatus. Operating parameters were selected to simulate conditions normally employed during the operation of large scale oxygen purifiers. Carbon dioxide impurity levels were nearly constant throughout each adsorption run, but ranged between 10 and 50 ppm from trial to trial. Therefore, the carbon dioxide adsorption capacity of the 13X molecular sieve could be determined as a function of varying, but very low, carbon dioxide impurity concentrations in oxygen.
