| 제목 | Effect of metal oxides on Cu/ZnO based catalysts for methanol synthesis from various ratio of CO/CO2 and H2 |
| 초록 | As emission standards have limited CO2 emission strictly, interests on carbon dioxide capture, storage and utility has been increased. Methanol synthesis process is one of the most promising solution to greenhouse effect because methanol is synthesized by syngas(H2+CO) and CO2. Existing commercial catalysts are based on Cu/ZnO/Al2O3 catalysts. These catalysts are effective for high ratio of CO/CO2, but methanol yield is sharply decreased at low ratio of CO/CO2. For this reason, research of new catalysts on methanol synthesis is required to accomplish high conversion of CO2 and yield of methanol. In this research, metal oxides (Ce, Mg, Zr, Al, Ga) were added to Cu/ZnO based catalyst by co-precipitation method. Ratio of CO/CO2, reaction temperature and pressure were varied to find out optimum reaction condition. Throughout the experiments, Cu/ZnO/ZrO2 catalyst showed high conversion of CO2 and yield of methanol among Cu/ZnO based catalysts. As the ratio of CO/CO2 was decreased, yield of methanol was decreased, but conversion of CO2 was increased. |
