ABSTRACT
Methane autothermal reforming with CO2, steam and O2 to synthesis gas over structured catalysts based on perovskites. The auto-thermal methane reformation over perovskite oxide supported on metallic structures has been studied. Catalytic tests with perovskite oxide synthesized by sol-gel method and supported on metallic structures by washcoating were carried out in a system reaction. Through characterization techniques confirmed the obtaining of perovskite and the homogeneity in the covering of structures. The best reactions conditions obtained were 750 ºC and molar ratio feed CH4/CO2/O2/H2O of 1/1/0.5/0.83. Under these conditions the performance of catalyst in powder was compared with the structured catalyst, a higher catalytic activity was observed with the structured catalyst.
