Hydrogen production by glycerol steam reforming: How Mg doping affects the catalytic behaviour of Ni/Al2O3 catalysts

Glycerol steam reforming, using Mg doped Ni/Al2O3 catalysts, was investigated with the aim to efficiently produce hydrogen. Catalyst containing different Mg loading were prepared by impregnation method maintaining constant the Ni loading (10 wt.%). Catalytic experiments were performed in fixed bed r...

By operating at 600 °C and with H2O/Gly ratio of 6, low amount of coke, mainly of filamentous nature, was formed. The size and structure of carbon filaments changed as a function of Ni particle size and Mg loading. Copyright © 2015, Hydrogen Energy Publications, LLC.
