The adsorbent includes at least 50 wt.% of faujasite. Faujasite is prepd. by (i) ion exchanging an adsorbent contg. faujasite for exchanging polyvalent ion and (ii) thermal activation of polyvalent ion exchanged adsorbent to eliminate essentially zoolitic water. The thermal activation process compri...
