Abstract: Microchannel devices and method of use are disclosed wherein a reaction microchamber (52) is in thermal contact with a heat exchange channel (61). An equilibrium limited exothermic chemical process occurs in the reaction microchamber (52). Sufficient heat is transferred to the heat exchange channels to substantially lower the temperature in the reaction microchamber (52) down its length to substantially increase at least one performance parameter of the exothermic chemical process relative to isothermal operation. Optionally, an endothermic reaction occurs in the heat exchange channel (61) which is sustained by the exothermic chemical process occurring the exothermic reaction chamber. Both the reaction chamber (52) and the heat exchange channel (61) can be of micro dimension. Catalyst (75) can be provided in the microchamber (52) in sheet form such that reactants flow by the catalyst sheet. A microchannel reactor (100) can be formed by integrally bonding an alternating stack of thin recessed sheets wherein the recesses in the sheets define the flow paths.

Abstract: The present invention is a method and apparatus (vessel) for providing a heat transfer rate from a reaction chamber through a wall to a heat transfer chamber substantially matching a local heat transfer rate of a catalytic thermal chemical reaction. The key to the invention is a thermal distance defined on a cross-sectional plane through the vessel inclusive of a heat transfer chamber, reaction chamber and a wall between the chambers. The cross-sectional plane is perpendicular to a bulk flow direction of the reactant stream, and the thermal distance is a distance between a coolest position and a hottest position on the cross-sectional plane. The thermal distance is of a length wherein the heat transfer rate from the reaction chamber to the heat transfer chamber substantially matches the local heat transfer rate.

Abstract: The present invention provides compact adsorption systems that are capable o f rapid temperature swings and rapid cycling. Novel methods of thermal swing adsorption and thermally-enhanced pressure swing adsorption are also described. In some aspects of the invention, a gas is passed through the adsorbent thus allowing heat exchangers to be very close to all portions of the adsorbent and utilize less space. In another aspect, the adsorption medi a is selectively heated, thus reducing energy costs. Methods and systems for g as adsorption/desorption having improved energy efficiency with capability of short cycle times are also described. In another aspect, the apparatus or methods utilize heat exchange channels of varying lengths that have volumes controlled to provide equal heat fluxes. Methods of fuel cell startup are al so described. Advantages of the invention include the ability to use (typically ) 30-100 times less adsorbent compared to conventional systems.
