چکیده مقاله:
The influence of Ni –MgO particle size on catalyst performance, product selectivity and coke formation in simultaneous steam and CO2 reforming of methane to syngas has been investigated.The Ni-MgO nanoparticles were prepared by the incipient wetness impregnation method. In this work, the Ni-MgO particle sizes in the range of 7/13 to 29/7 nm have been studied using well-defined Catalysts based on α-Al2O3 support.Experimental results indicated that both products selectivity’s and H2/CO ratio to be independent of Ni-MgO particle size. Nevertheless, formation rates on the surface of catalyst are increased by increasing Ni-MgO particle size. In addition, the carbon atoms deposited on one site of catalyst is shawn an opposite trend.
