摘要：

A series of Co/Mg-Al oxide samples, CoMgAl-x (x = (Mg + Co)/Al molar ratio of 1-5), were prepared by the self-combustion method followed by H-2 reduction. The catalytic performance and stability of the samples were studied in dry reforming of CH4. XRD and H-2-TPR characterization results showed that the reduced CoMgAl-x samples mainly consisted of solid solution and spinel phases with cobalt particles. The spinel phases contained Co3O4 and ConMg1-nAl2O4 (0 <= n <= 1) varying with the (Mg + Co)/Al ratio. The effect of (Mg + Co)/Al molar ratio on the catalytic behavior was investigated in detail and CoMgAl-3 exhibited the highest catalytic activity and stability among the catalysts studied.
