5 wt % Ni\SiO2 catalyst for producing H2\CO form methane by CO2 reforming was prepared by three methods using Citric acid with diferent concentration and mixture of NH3 and water by sol–gel process. All the catalysts prepared with the above methods were calcined at 500 ˚C. After reduction, catalytic activity toward CO2 reforming of CH4 with CO2\CH4 ratio equal to 1 was tested in a fixed bed reactor at 700, 750 and 800˚C. It was found that CO2 and CH4 conversion was similar for all methods in this work. The results demonstrated that the conversions of CO2 and CH4 and the H2\CO ratio was 0.92,0.94and 1.09 respectively<\div>
