Abstract
Embodiments of a rapid cycle PSA apparatus are described that are useful for producing a hydrogen enriched product gas comprising not more than about 50 ppm carbon monoxide by volume and with a hydrogen gas recovery of at least about 70% by adsorptive separation from a syngas feed gas mixture comprising at least about 50 percent hydrogen and at least about 1 percent carbon monoxide by volume. One disclosed embodiment of a rapid cycle PSA apparatus comprised at least 3 adsorber elements each having at least one thin adsorbent sheet material which comprises at least one adsorbent material therein, and a bed size factor less than about 4.0 seconds. Embodiments of a rapid cycle PSA process also are described that utilize disclosed embodiments of the rapid-cycle PSA device.
