    摘要： 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.

    摘要： High density adsorbent structures may be constructed in parallel passage contactor configurations using improved high density adsorbent sheets. Improved high density adsorbent sheets may be formed using adsorptively active support or substrate materials upon which adsorbent material is applied, such as by coating processes, so that in the resulting high density adsorbent structure both the substrate and the coated adsorbent material are active in adsorption processes. Alternatively, improved high density adsorbent sheets may be formed comprising precursor materials, such as certain clays, which may be coated onto known support materials and thereafter converted to active adsorbent materials using known conversion techniques. This produces high-density adsorbent sheets comprising adsorbent material without inert binder material fractions. Improved self-supporting adsorbent sheets also may be formed without using support material, resulting in higher adsorbent densities relative to known adsorbent sheets.
