Catalytic performance of the perovskite-like NiSrOx on the modified SiC support for the combined steam reforming of CH4 and CO2 |
| 초록 |
The nickel containing perovskite-like (La)NiSrOx catalysts on the modified SiC support were investigated for the combined steam reforming reaction of CH4 with CO2. The (La)NiSrOx perovskite-like catalysts showed a lower sintering character of nickel particles and a lower coke formation. The SiC support was previously modified with Al2O3 or MgAl2O4 component to enhance the dispersion of (La)NiSrOx perovskite-like particles. At optimum content of Al2O3 or MgAl2O4 modifier on SiC support, the catalyst showed an enhanced CO2 conversion by increasing the adsorption properties of CO2 on the basic La or Sr oxides. The optimum concentration of modifier was found to be around 10wt% Al2O3 and MgAl2O4 on SiC support. The suppressed aggregation of nickel-containing particles was also attributed to the strong interaction between Ni and modifier. The different catalytic behaviors were explained by characterizing the surface properties such as Ni particle sizes and basic properties through XRD, XPS, BET and TEM analyses. |
