abstract
Microchemical reaction engineering for biofuel-driven portable power systems was studied. Reaction and diffusion considerations in non-isothermal microreactor and micro-membrane reformers, and heat integration and stability considerations for multifunctional microreactors were investigated. Significant improvement in reactor design can be achieved with appropriate manipulation of reactor and catalyst structures. Microchemical systems, comprised of large networks of parallel, separate channels promise efficient heat transfer between endo- and exothermic processes, e.g., partial oxidation and water-gas-shift. Selection of appropriate geometries, materials, and packaging showed significant effects on both thermal efficiency and steady-state multiplicity. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake, UT 11/4-9/2007).
