ABSTRACT:
The present invention relates to a process for the selective adsorption and separation of one or more constituents from a gas stream in a gas chromatograph, wherein the gas stream is contacted with a dehydrated chabazite adsorbent having a residual water content of less than 1.5 wt. % and having at least 50% of any exchangeable ion capacity exchanged with a polyvalent metal cation and wherein the dehydrated chabazite has been reacted with an oxidizing atmosphere either during or following dehydration. The process of the present invention both anticipates separation of the constituents due to either a difference in the heats of adsorption of the constituents or a size exclusion effect.
