Abstract

Carbon formation behavior under CH₄-CO₂ reaction and through CH₄ decomposition and CO disproportionation was investigated over Ni_0.03Mg_0.97O solid solution, supported Ni/MgO, and NiO-Al₂O₃ catalysts by means of thermogravimetric analysis (TGA) and transmission electron microscopy (TEM). Ni_0.03Mg_0.97O showed high resistance to carbon formation in CO₂ reforming of methane and the selectivity to carbon formation was much lower than two other catalysts. It is suggested that CO₂ plays an important role in the inhibition of carbon formation on Ni_0.03Mg_0.97O through the activation of CO₂ at the interface between small nickel particles and the support surface.
