BINDERLESS ZEOLITIC ADSORBENTS, METHODS FOR PRODUCING BINDERLESS ZEOLITIC ADSORBENTS, AND ADSORPTIVE SEPARATION PROCESSES USING THE BINDERLESS ZEOLITIC ADSORBENTS

摘要

Binderless BaKX zeolitic adsorbents, methods for their production, and adsorptive separation using the adsorbents are provided. An adsorbent comprises a first Zeolite X having a silica to alumina molar ratio of from about 2.0 to about 3.0; a binder-converted Zeolite X wherein a ratio of the binder-converted Zeolite X to the first Zeolite X ranges from about 10:90 to about 20:80 by weight; and barium and potassium at cationic exchangeable sites within the binderless BaKX zeolitic adsorbent. Potassium ranges from about 0.9 wt % to about 1.5 wt % and barium ranges from about 30 wt % to about 34 wt % of the binderless BaKX zeolitic adsorbent.
