%X Cenospheres from coal fly ashes were used as support in the preparation of Ni¨CMg catalysts for dry reforming of methane. These materials were characterized by means of XRD, H 2-temperature-programmed reduction (H 2-TPR), CO 2-temperature-programmed desorption (CO 2-TPD), and low-temperature nitrogen sorption techniques. The cenosphere-supported catalysts showed relatively high activity and good stability in the dry reforming of methane (DRM) at 700 ¡ãC. The catalytic performance of modified cenospheres was found to depend on both Ni and Mg content. The highest activity at 750 ¡ãC and 1 atm was observed for the catalyst containing 30 wt % Mg and 10, 20, and 30 wt % Ni, yielding to CO 2 and CH 4 conversions of around 95%. View Full-Tex
