Steam reforming of glycerol over Ni/Mg/γ-Al 2O 3 catalysts. Effect of calcination temperatures
The aim of this work is to study the catalytic activity of Ni(10%) based catalysts supported over ã-Al 2O 3 modified with Mg (3%) for the steam reforming of glycerol. Catalysts have been prepared by incipient wetness impregnation method; analysing the effect of the calcination temperature of the mod...
