Ni/Al-Mg-O solids modified with Co or Cu for the catalytic steam reforming of bio-oil

► Ni/AlMg catalysts modified with Cu or Co and prepared by impregnation and coprecipitation. ► Study of the catalyst performance using one-way ANOVA analysis and the multiple LSD test. ► Significant improvement with the NiCo/AlMg catalyst prepared by coprecipitation. ► Comparison of the catalyst performance in fixed bed and fluidized bed reactors.
