 Steam CO2 reforming(SCR) reaction of methane for the production of syngas was investigated over Ni based catalysts. The Ni based catalysts were prepared by the solid phase crystallization and impregnation methods. The catalysts before and after the reaction were characterized by N2 physisorption, CO chemisorption, TPR, XRD, SEM and TEM techniques. The H2/CO ratio produced in the SCR of methane showed a strong dependence on the feed composition. The conversion of CH4 was increased with increasing the concentration of steam and CO2 in the feed. For Fischer-Tropsch synthesis reaction, the feed ratio of CH4/H2O/CO2 for the production of H2/CO=2 was estimated by the modeling of commercial simulation package, and identified in the fixed bed reactor system. It was found that the Ca modified Ni based hydrotalcite catalyst showd higher catalytic stability with the restriction of the carbon formation in the SCR of methane under the tested condition.
