| 제목 | Methanol Synthesis over Cu-ZnO-Al2O3-ZrO2-SiO2 Catalysts Prepared by Different Methods |
| 초록 | Methanol synthesis is one of the promising processes in the chemical engineering field as utilization of gas to liquid technologies particularly from syngas. In this work, Cu-ZnO-Al2O3-ZrO2-SiO2 catalysts have been prepared by different methods such as impregnation, co precipitation, hydrothermal and polyol reduction methods. All catalysts have been characterized by BET surface area, TPR, TG/DTA, XRD and XPS for structure elucidation. All catalysts were examined for methanol synthesis from syngas under 40 bar pressure, with GHSV 3500 h-1. The characterization results considered that the preparation method of catalysts can be changed the dispersion of metal, metal–support interactions and particle size of active species. The results suggest that the method of preparation is played a crucial role in the CO hydrogenation and methanol yield. |
