Size-controled synthesis of NiO-MgO nanoparticles in CO2-steam reforming of methane

Abstract

The influence of Ni –MgO particle size on catalyst performance, product selectivity and coke formation in<br><br>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 to29/7 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<br><br>site of catalyst is shawn an opposite trend.
