CH₄/CO₂ reforming to syngas over Mg-Ni/BaTiO₃ catalyst

A series of Mg-Ni/BaTiO₃ catalysts (Ni/BaTiO₃ promoted by MgO) were prepared by impregnation method; their catalytic activity for CH₄/CO₂ reforming to syngas was examined with a fixed bed reactor. The results showed that Mg-Ni/BaTiO₃ catalyst with an MgO loading of 5% performs best in CH₄/CO₂ reforming. The sequence for impregnation during the catalyst preparation may also influence the activity of resultant catalyst; Mg should be impregnated prior to Ni to get high active Mg-Ni/BaTiO₃ catalyst. Compared with Ni/BaTiO₃, the addition of MgO promoter can enhance its catalytic activity and resistance to carbon deposition for CH₄/CO₂ reforming.
