METHOD TO REGENERATE ADSORBENT IN A PRESSURE SWING ADSORPTION PROCESS

摘要

The present invention relates to a method to remove one or more contaminant from a gas stream, preferably a hydrocarbon gas steam, using a solid adsorbent, preferably a porous cross-linked polymeric adsorbent, a pyrolized macroporous polymer, or mixtures thereof and regenerating said adsorbent by an improved pressure swing adsorption process wherein a portion of the product gas is heated and used as the purge gas.
