Impact of Support Type on Nickel‐Based Catalysts for the Dry Reforming of Methane

Energy Science &Engineering, EarlyView.
ABSTRACT This study investigates the catalytic efficiency of Ni catalysts for the dry reforming of methane, utilizing different metal oxides (CeO₂, SiO₂, SmO₃, and YO₃) support. The impact of the support material on the conversion of CH₄ and CO₂, as well as the resulting H₂/CO ratio, is investigated at 700°C and 800°C.
