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. 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.
