Adsorbents and adsorptive separation process

摘要

Porous composite (C) comprises (wt.%) microparticulate zeolite (40 - 95) and a binder (5 - 60). At least 90% of zeolite has a particle size not greater than about 0.6 micron. An independent claim is also included for separating a component from a gas mixture which involves: (a) passing the mixture through at least one adsorption zone at selected temperature and pressure. The zone contains (C) as the adsorbent to preferentially adsorb the component; and (b) regenerating the adsorbent at a temperature higher than the selected temperature and/or at a pressure lower than selected pressure.
