ABSTRACT:
Microchannel devices and method of use are disclosed wherein a reaction microchamber52is in thermal contact with a heat exchange channel61. An equilibrium limited exothermic chemical process occurs in the reaction microchamber52. Sufficient heat is transferred to the heat exchange channels to substantially lower the temperature in the reaction microchamber52down 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 channel61which is sustained by the exothermic chemical process occurring the exothermic reaction chamber. Both the reaction chamber52and the heat exchange channel61can be of micro dimension. Catalyst75can be provided in the microchamber52in sheet form such that reactants flow by the catalyst sheet. A microchannel reactor100can be formed by integrally bonding an alternating stack of thin recessed sheets wherein the recesses in the sheets define the flow paths.
