Abstract
Method for the separation of a gas mixture comprising providing a PSA system with at least one adsorber vessel containing adsorbent material that is selective for the adsorption of carbon monoxide and nitrogen, passing a feed gas mixture containing at least hydrogen and carbon monoxide and optionally containing nitrogen through the adsorbent material in a feed step and withdrawing a purified hydrogen product from the adsorber vessel, wherein the feed step has a duration or feed time period of about 30 seconds or less. The adsorbent material is characterized by any of (1) a Henry's law constant for carbon monoxide between about 2.5 and about 5.5 (mmole/g)/atm; (2) a carbon monoxide heat of adsorption between about 6.0 and about 7.5 kcal/gmole; (3) a Henry's law constant for nitrogen greater than about 1.5 (mmole/g)/atm; and (4) a selectivity of carbon monoxide to nitrogen between about 5.0 and about 8.0.
