TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The absorber device (b) includes several vessels, each operating in one of adsorption, equalization, blow-down, purge or pressurization. The device (b) includes a first and second adsorbents. The device (b) adsorbs carbon monoxide, carbon dioxide, nitrogen, water, light hydrocarbons (e.g. methane, ethane, ethylene, propane and propylene), heavier hydrocarbons (e.g. unreacted gasoline), and other trace impurities (e.g. ammonia and hydrogen sulfide). The reformate gas comprises available hydrogen (at least, 70, preferably 87)%. The reformate gas enters the adsorber device at a pressure of 1.5-7 bar. A portion of the stream of hydrogen gas is used to purge an adsorbent in the adsorber device. The device (b) is a rapid-cycle pressure swing adsorber (PSA) device. The PSA device includes a rotating adsorbent bed or a rotary valve.Preferred System: The processing system (S1) further comprises a water/gas shift (WGS) reactor for receiving reformate gas (G1) prior to being applied to the device (b) and converts carbon monoxide and water to hydrogen and carbon dioxide and generating a reformate gas that is primarily hydrogen, nitrogen, carbon monoxide, carbon dioxide and water; a liquid water separator for receiving (G1) and separating liquid water to generate a reformate gas containing primarily hydrogen, nitrogen, water vapor, carbon monoxide and carbon dioxide; a heat exchanger for cooling (G1) prior to being applied to the liquid water separator; first heat exchanger and a mixing valve for generating a steam/air mixture to be sent to the primary reactor (a) and for heating and vaporizing liquid water, and mixing the steam with compressed air; a second heat exchanger for receiving the steam/air mixture from the mixing valve before it sent to (a), and receiving (G1) from (a) and heating the steam/air mixture prior to being sent (a) and cooling the reformate gas; combustor for generating heat that is applied to vaporize steam to be fed to (a) to generate the hydrogen from the hydrocarbon fuel; heater for receiving (G1) and heating at 5-10 degrees C prior to being sent to (b) to prevent liquid water from condensing in (b); and water vapor transfer device selected from a membrane device and an adsorption device for receiving (G1) before it being applied to(b), to remove water vapor from (G1).The WGS reactor includes an adsorbent for adsorbing carbon monoxide, and a combination of at least one of a high temperature WGS reactor, a medium temperature WGS reactor or a low temperature WGS reactor. The system is a stand-alone unit and coupled to a fuel cell (e.g. vehicle) for generating electricity.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The first absorbent is activated carbon, alumina, or zeolites, such as type 5A and/or type 13X. The zeolites contain alkaline or alkaline earth cations, such as sodium, potassium, lithium and/or calcium. The second absorbent is zeolites (e.g. type A, X, Y or mordenite), alumina and/or activated carbon. The second absorbent is impregnated with a copper and/or silver salt.
