제목 | Comparison of Methanol and Higher Alcohol Synthesis over Cu/ZnO/Al2O3 Catalyst |
초록 | Increasing concerns over reducing pollution and emission such as NOx, CO, and unburned hydrocarbon in the exhaust, higher alcohol has been considered as gasoline additive for oxygenation of conventional fuel and for gasoline octane enhancer. In this work, Cu/ZnO/Al2O3 catalysts were prepared under different pH conditions in co-precipitation step and the lithium were promoted on Cu/ZnO/Al2O3 catalysts via impregnation step. The purpose of this work is comparing Methanol Synthesis (MS) with Higher Alcohol Synthesis (HAS). All catalysts were characterized by N2 physisorption, XRD, XRF, H2-TPR/TPD. The reaction was carried out under the pressure of 45 bar, the GHSV of 4000 h-1, the molar ratio of H2/CO = 1, and the temperature of 240 °C for MS and 280 °C for HAS. It was found that the catalyst with a large amount of malachite phase is favorable for methanol synthesis and the selectivity to higher alcohol was correlated with Cu surface area. |
