| 제목 | Studies on Alkali Promoted Cu/ZnO/Al2O3 Catalyst for Higher Alcohol Synthesis |
| 초록 | As concerns over global climate crisis has been increased, many researcher have studied the alternative fuels. Higher alcohol, including C2-C4 alcohol, has been considered as gasoline additives for oxygenation of conventional fuels and for gasoline octane enhancer. In this work, the alkali metal promoted (Li, K, Sr, and Cs) Cu/ZnO/Al2O3 catalyst for Higher Alcohol Synthesis (HAS) were prepared by impregnation method and characterized by N2 physisorption, XRD, XRF, H2-TPR/TPD. The HAS reaction was carried out under the pressure of 45 bar, feed molar ratios of H2/CO = 1-2, temperature ranges of 240-280 °C and GHSV = 4000 h-1. It was identified that the higher electronegativity of the promoter makes more adsorption of carbon monoxide on Cu and it could favor the CO insertion and the production of C2+ alcohols. |
