Steam CO₂ reforming of methane over Ni-based perovskite type catalyst was investigated to produce hydrogen-rich gas for applications in hydrogen station and fuel cell process. Ni-based perovskites were prepared by the Pechini method and calcined in air. The catalysts before and after the reaction were characterized by N₂physisoprtion, CO chemisoprtion, XRD, TPR, SEM and TEM techniques. To obtain hydrogen-rich gas, simulations for SCR and SR were carried out by commercial simulation program, and catalytic performance was evaluated in a fixed bed reactor system using feed ratio estimated by simulation. The results suggest that the hydrogen-rich syngas produced by SCR and SR of methane can be applied to SOFC and MCFC systems.
