Catalytic performance on CuO-Cr2O3-Ga2O3 mixed oxides for water gas shift reaction: effects of Ga/Cr molar ratio |
| 초록 |
Water gas shift (WGS) reaction was carried out on the co-precipitated CuO-Cr2O3-Ga2O3 mixed oxides by varying the molar ratio of Ga/Cr using metal nitrate precursors and Na2CO3 precipitant. The catalytic was prepared at the fixed molar ratio of Cu/(Cr+Ga) at 1.0/0.1 with the different Ga/Cr ratio from 0 to 4. The catlalytic performance on the reduced CuO-Cr2O3-Ga2O3 mixed oxides is found to be in the shape of volcano curve with respect to the variation of Ga/Cr molar ratio. The highest catalytic activity was observed at the molar ratio of Ga/Cr = 1.0 in the temperature ranges of 160 280 oC. The observed catalytic activities are strongly related with the metallic surface area and crystallite size of Cu species which are confirmed by XRD and N2O titration method. |
