A co-precipitation method was used for the synthesis of a novel copper-ceria catalyst promoted with gallium. Structural characterization was performed by SEM, EDS, BET, XRD, and XPS techniques. Methanol steam reforming was conducted inside a miniaturized LTCC packed bed reactor in the temperature range of 300-400 degrees C, and hydrogen was successfully produced from a water and methanol mixture. The kinetics of the reforming process were evaluated and the operation of the miniaturized reactor was described with a 3D finite element model, which included all governing mechanisms: fluid dynamics, transport phenomena and reaction kinetics.
