<p>A compact modular isothermal reactor (40) for converting a feedstock such as methanol into a fuel usable in power generation systems, such as electrochemical fuel cells, is provided. The reactor includes a sealing plate (48), a baffle plate (45) having heat transfer surfaces (47) extending toward the sealing plate (48), and a housing (46) having an interior substantially circumscribing the heat transfer surfaces (47). The cooperating surfaces of the sealing plate (48), baffle plate (45), heat transfer surfaces (47) and housing interior define a tortuous or labyrinthine channel for containing a suitable quantity of solid catalyst (62) and through which feedstock flows. The cooperating surfaces of a fluid flow plate (44) and the baffle plate (45) define a flow passage (50) for carrying a thermal fluid. Heat is transferred from the thermal fluid to the feedstock by the heat transfer surfaces (47). In two alternative designs, thermally conductive pins (78, 81) extending from the fluid flow plates (76, 83) or a pair of spaced folded thermally conductive plates (107) transfer heat to the interior of a catalyst containment vessel (106). In an optional heat exchange section (11), the feedstock is preheated before being directed to the reactor.</p> |
