Studies on carbon deposition in CO{sub 2} reforming of CH{sub 4} over nickel-magnesia solid solution catalysts
- Univ. of Tokyo (Japan)
Carbon formation behavior under CH{sub 4}-CO{sub 2} reaction and through CH{sub 4} decomposition and CO disproportionation was investigated over Ni{sub 0.03}Mg{sub 0.97}O solid solution, supported Ni/MgO, and NiO-Al{sub 2}O{sub 3} catalysts by means of thermogravimetric analysis (TGA) and transmission electron microscopy (TEM). Ni{sub 0.03}Mg{sub 0.97}O showed high resistance to carbon formation in CO{sub 2} reforming of methane and the selectivity to carbon formation was much lower than two other catalysts. It is suggested that CO{sub 2} plays an important role in the inhibition of carbon formation on Ni{sub 0.03}Mg{sub 0.97}O through the activation of CO{sub 2} at the interface between small nickel particles and the support surface.
