Patent ID: 8283274

Claim:
A binderless BaKX zeolitic adsorbent comprising: a binder-converted zeolite portion formed from x wt % inert clay binder, wherein x is in the range of about 10 to about 20% by weight of the binderless BaKX zeolitic adsorbent; (100-x) wt % Zeolite X with a silica: alumina molar ratio of about 2.5±0.5; and barium (Ba) and potassium (K) at cationic exchangeable sites within the binderless BaKX zeolitic adsorbent, wherein K is in the range of about 0.25 to about 0.9% by weight and the Ba is greater than about 31.6% by weight of the binderless BaKX zeolitic adsorbent; and wherein a total pore volume of the binderless BaKX zeolitic adsorbent measured by Hg intrusion porosimetry is between 0.25 cc/g and 0.35 cc/g.
