| 中文摘要 | Methanol synthesis fromhydrogenation of CO2 is investigated over Cu/ZnO/Al2O3 catalysts prepared by decomposition ofM(Cu,Zn)-ammonia complexes (DMAC) at various temperatures. The catalysts were characterized in detail, including X-ray diffraction, N2 adsorption-desorption, N2O chemisorption, temperature-programmed reduction and evolved gas analyses. The influences of DMAC temperature, reaction temperature and specific Cu surface area on catalytic performance are investigated. It is considered that the aurichalcite phase in the precursor plays a key role in improving the physiochemical properties and activities of the final catalysts. The catalyst from rich-aurichalcite precursor exhibits large specific Cu surface area and high space time yield of methanol (212 g/(Lcat·h); T = 513 K, p = 3 MPa, SV = 12000 h−1). |
