Abstract
Embodiments of the invention are directed to methods, processes, and systems for safely and reliably purifying hydrogen from a gas mixture containing hydrogen and oxygen.
Claims20
A process for separating hydrogen and oxygen from a gas mixture comprising:
- separating the hydrogen and the oxygen at about atmospheric pressure by passing the feed source through an adsorption medium comprising a carbon molecular sieve that selectively adsorbs hydrogen from the feed source producing an enriched oxygen product gas and an adsorption medium enriched in hydrogen;
- and
- desorbing the adsorbed hydrogen by exposing the hydrogen enriched adsorption medium to a vacuum forming a hydrogen enriched purge gas and a regenerated adsorption medium.
A process for separating hydrogen and oxygen comprising:
- providing a gas mixture feed comprising oxygen and hydrogen;
- passing the gas mixture feed through an adsorption medium that selectively adsorbs hydrogen from the gas mixture feed producing a hydrogen enriched adsorption medium;
- desorbing the adsorbed hydrogen by exposing the hydrogen enriched adsorption medium to a vacuum forming a hydrogen enriched purge gas and a regenerated adsorption medium, and
- injecting a hydrogen product gas to the gas mixture feed.
