A Ni/Ce-Zr-Al-Ox catalyst was prepared by hydrothermal synthesis-impregnation method. The CO2 reforming of CH4 reaction was performed. By XPS and TPH methods the carbon species deposited on the surface of catalyst during the reaction were characterized; The effect on the carbon deposit by adding a small amount of steam in feed gas and the interaction between steam and carbon species were studied. The results obtained show that there are mainly two types of carbon species :α-carbon appearing at 250~350 ℃ should be mainly CH4 decomposed fragment which shows reactive to hydrogenation; β-carbon appearing at about 700 ℃ should be the unreactive carbon which tends to be graphite or is graphitized carbon and is responsible for catalyst deactivation. β-carbon is easier to react with steam than α-carbon, therefore adding a small amount of steam in feed gas can obviously suppress β-carbon deposit. The activity test shows that the Ni/Ce-Zr-Al-Ox catalyst has a CH4 conversion of 89% and a od stability, and the CH4 conversion increases to 94% by adding 3.2%(φ) steam. In addition, due to the suppression to unreactive carbon, it can be expected that the stability of catalyst will be further promoted.
