Abstract
A rapid pressure swing adsorption (RPSA) process includes the use of an adsorbent fabric. The fabric can be self-supporting, have an average pore diameter greater than 5 Å and/or have a carbon dioxide mass transfer coefficient of at least 0.5 sec . Activated carbon cloths can be suitable for use as the adsorbent fabric. The process can be used to prepare high purity hydrogen and other products. Systems including the adsorbent fabric outperform systems lacking such fabrics in RPSA applications.
