• A novel copper–ceria catalyst promoted with gallium was synthesized.
• XRD revealed that the structure corresponded to the cubic fluorite CeO2.
• Methanol steam reforming inside a packed-bed miniaturized reactor was studied.
• A 3D finite element model was used to describe the process.
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 °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.
