ABSTRACT:
Methods and systems for pressure swing absorption for hydrogen generation are presented. In one embodiment, a method includes absorbing at least one oxide of carbon with a pressure swing absorber from a steam reformation of methane. The steam reformation may occur at an ambient pressure in excess of 300 psia and at an ambient temperature in excess of 600° centigrade. The steam reformation of methane produces a stream of product gas. The steam reformation of methane is interrupted allowing the regenerating of the pressure swing absorber at an ambient pressure of less than 10 psia and at an ambient temperature sufficient to calcine the pressure swing absorber to exude carbon dioxide.
