Carbon Dioxide Reforming of Methane over Ni/Mo/La₂O₃-SBA-15 Сatalyst

Abstract:

Carbon dioxide reforming of methane over Ni/Mo/ La₂O₃-SBA-15 was studied. The catalyst was characterized by N₂ adsorption, X-ray diffraction, H₂-TPR,CO₂-TPD and TG-GTA analysis. The results indicated that the introduction of an appropriate amount of La₂O₃ exhibited a higher activity and stability. In the long term stability test, La₂O₃ impregnated Ni/Mo-SBA-15 gave the highest conversion and stable activity at 800°C for 250 h. The effect of La was suggested to be due to its lower tendency to carbon deposition. Characterization results showed a strong interaction between La and Mo or Ni which facilitated the improvement of catalytic performance.
