Abstract

Ni/γ-Al2O3, CoNi/γ-Al2O 3, and MgCoNi/γ-Al2O3 catalysts have been applied for the carbon dioxide reforming of methane reaction (CDR) and coke formation in the used catalysts has been investigated to understand the beneficial effect of Mg and Co. The MgCoNi/γ-Al2O3 catalyst exhibits the highest catalytic performance (XCH4 > 95% for 200 h) and has high coke resistance in CDR. This is due to the addition of Mg and Co accelerates the decomposition/dissociation of CH4 and CO2.
