Abstract

Higher alcohol has been considered as a potential fuel additive. Higher alcohol, including C2–C4 alcohol was synthesized by catalytic conversion of syngas (with a ratio of CO/H2 = 1) derived from natural gas over modified Cu/ZnO/Al2O3 catalyst. Modified Cu/ZnO/Al2O3 catalysts promoted by alkali metal (Li) for higher alcohol synthesis (HAS) were prepared at different pH (6, 6.5, 7, 8, and 9) by co-precipitation to control Cu surface area and characterized by N2 physisorption, XRD, SEM, H2-TPR and TPD. The HAS reaction was carried out under a pressure of 45 bar, GHSV of 4000 h−1, ratio of H2/CO = 1, and temperature ranges of 240 and 280 °C. It was found that the malachite phase of copper causes the size of copper to be small, which is suitable for methanol synthesis. Methanol and HAS share a common catalytic active site and intermediate. It was also found that the productivity to higher alcohol was correlated with Cu surface area.
