CH4-CO2 reforming reaction can realize the utilization of CH4 and CO2,which is of great significance to curb the greenhouse effect and environmental protection. Developing the reforming catalysts with low cost,high activity and high stability is of critical importance. Supported Ni/Q10(amorphous SiO2 with 10 nm pores) and embedded Ni@S1(Silicalite-1) catalysts were prepared by impregnation method and grinding-crystallization method,respectively,and they were used in CH4-CO2 reforming reaction. The structure of the catalyst was characterized by XRD,BET,IR,H2-TPR,NH3-TPD,XRF,XPS,SEM,TEM and TG. It is found that the grinding-crystallization method can effectively control the particle size and dispersion of active metal Ni in Ni@S1 catalyst,and enhance the interaction between active metal phase and carrier. The intercalation structure can reduce the carbon deposition of the catalyst,after reacting at 700 ℃ for 6 h,the carbon deposition of 5% Ni@S1 catalyst is only 46.83% of that of 5% Ni/Q10 catalyst. The activity of the catalyst was evaluated in a continuous fixed-bed reactor (CH4/CO2/Ar=44.0/47.2/8.8,Fin=40 mL/min,T=700 ℃). It is found that the instantaneous conversion of CH4 over 5% Ni@S1 and 5% Ni/Q10 catalysts are 72.82% and 67.24%,respectively,which decreases by 1.05% and 7.99% compared with the initial conversion rates.The instantaneous conversion rate of CO2 are 79.06% and 76.69% respectively,which are 1.16% and 4.54% lower than the initial conversion rates.The activity and stability of embedded Ni@S1 catalyst for CH4-CO2 reforming reaction are superier to those of supported Ni/Q10 catalyst.
