The dry reforming reaction of methane comes as a promising process of syngas and hydrogen. Nickel catalysts on Al2O3 and SiO2 were synthesized by sol-gel method, with metalic load of 8% weight. The catalysts were characterized by temperature programmed reduction (TPR), termogravimetry analysis (TGA) and specific surface area measurements (BET). The dry reforming reaction was performed in a micro reactor packed ...
