The results showed that NiCu alloy

The results showed that NiCu alloy had improved catalyst performance compared to the monometallic Cu for methanol and ethanol reforming. It was also demonstrated that the introduction of Cu in the catalyst formulation suppresses coke deposition and the sintering of the active phase in steam reforming. The addition of Cu revealed a positive effect by preventing the formation of methane with enhanced stability. The experiment was conducted by constant increase of the reaction temperature. However, it cannot prove whether the formation of CH4 from hydrogenation reaction was supressed as the temperature was increasing during the experiment,for which a study under steady operation conditions was required.
