Abstract
This paper reports the results obtained using CO2 reforming of CH4 for Mitigation of green house gases. The thy reforming of methane was carried out over 10 wt% Ni /S151-10 and 10 wt% Ni /TiO2 catalysts prepared by the wet impregnation method. In this study, the experiment was carried out in a micro tubular reactor at atmospheric pressure, using CO2:CH4 feed ratio of 1:1 and a total flow rate of 30 ml/min, reaction temperatures 500, 550, and 575 degrees C. Influence of calcination temperature, catalyst stability and synthesis gas ratio (H-2/CO) were studied It was obtained that CO2 and CH4 conversions increase with reaction temperature for specified calcination temperature. But the conversions usually decrease increasing the calcinations temperature. Catalysts calcined at 500 degrees C for both supports gave relatively lower carbon deposition in comparison with those calcined at 800 degrees C. On the other hand, the performance of catalysts supported by TiO2 is relatively higher than those supported by silica. This finding is verified by the conversions of feed gases and the determination of deactivation factors and the outcome of TGA characterization
