摘要
A very active catalyst of CuO/CeO2 was made by adsorption-impregnation method for preferential oxidation of CO in H-2. The CO conversion is close to 100% and selectivity to CO oxidation is 96% over this catalyst at a low reaction temperature of 95 degrees C and a space velocity of 40000 cm(3) center dot g (-1) center dot h (-1) in the reaction mixture of 1 % CO, 1 % O-2, and 50 % H-2 balanced with N-2. The effect of preparation conditions on catalytic performances was investigated. The catalytic performance of the CuO/CeO2 catalysts was compared with that of other CO preferential oxidation catalysts reported in literature.
