Artigo Nickel catalyst supported on magnesium and zinc aluminates (MgAl2 O4 and ZnAl2 O4 ) spinels for dry reforming of methane(Associação Brasileira de Cerâmica - ABCeram, 2017) Melo, Marcus Antônio de Freitas; Araújo, Larissa Costa Barros de; Melo, Dulce Maria de Araújo; Barros, J. M. de F.; Braga, Renata Martins; Costa, C. de C.; Rodrigues, G.Materials such as MgAl2O4 and ZnAl2O4 assessed in the reaction of dry reforming of methane to produce syngas were synthesized by microwave-assisted combustion method using urea as fuel. Samples of synthesized oxides were calcined at 800 °C for 2 h and impregnated with 5% nickel. The impregnated samples were calcined at 850 °C for 4 h to obtain the desired phases. The results of the catalytic tests showed that the catalysts are active for the reaction of dry reforming of methane, and the catalyst that showed the best performance for methane conversion was 5% Ni/MgAl2 O4 calcined at 850 °C/4h
