Catalytic activities and deactivation characteristics of nickel based catalyst for the reaction of carbon dioxide with Natural gas were investigated. 13 wt% Ni catalyst showed very high CH4 and CO2 conversions over 800 ℃. Among the catalysts prepared with various supports, conversion and yield were Ni/HY>Ni>γ-Al2O3>Ni/SiO2. There was no coke formation for reaction times.
