Template method was used to prepare ordered mesoporous alumina, and with purchased γ-Al2O3 contrast. BET results showed that the specific surface area and average pore diameter of the mesoporous Al2O3 were 226.95 m2.g-1 and 3.91nm respectively, and with higher degree of order. XRD results showed that the cat-P catalyst with the carrier of prepared ordered mesoporous alumina hold small active component grains, which means better dispersion. H2-TPR results showed that the SMSI effect of cat-P catalyst was stronger than that of cat-B. Stability tests showed that cat-P catalyst in 50h experiment showed high activity and stability, and the conversion of CH4 and CO2 were above 90% and 95% respectively among the reaction time, and the deactivation rate of CO2 was 0.05%/h only. From TG-DTG curve could be seen that the deposition carbon on cat-P catalyst after 48h reaction was in whisker form, which did not cover the active sites and had little influence on the activity and stability of the catalyst.
