Abstract

See full text

A hydrogen feed stream comprising one or more impurities selected from the group consisting of nitrogen, argon, methane, carbon monoxide, carbon dioxide, oxygen, and water, is purified using a cryogenic temperature swing adsorption (CTSA) process with high overall recovery of hydrogen. The waste gas from regenerating the CTSA may be used to improve the performance of upstream hydrogen processing steps.
