RETRACTED ARTICLE: Effect of Gd₂O₃ over Ni/SiO₂ on syngas production via methane autothermal reforming

摘要

Gd₂O₃-promoted Ni/SiO₂ catalysts exhibited higher activity and selectivity than Ni/SiO₂ in methane autothermal reforming. The results of the temperature-programmed surface reaction of CH₄ indicated that Gd₂O₃ might enhance anti-carbon deposition properties. The reactivity of surface carbons showed that the presence of Gd₂O₃ reduced the formation of inactive carbons on Ni/SiO₂. Raman results suggested that the order of graphitization of deposited carbon decreases with the addition of Gd₂O₃.
