Experimental study on hydrogenation of methyl acetate to fuel ethanol with copper-based catalyst
摘要
Abstract
Different copper-based catalysts manufactured in laboratory were evaluated in hydrogenation of methyl acetate to ethanol. The Cu-ZnO/Al2O3 catalyst was good but the Cu/ZnO catalyst was not. Methyl acetate hydrogenation over Cu-ZnO/Al2O3(Ⅱ)(30~60 mesh) was studied in a tubular reactor,and the influences of reaction temperature,space velocity,feed molar ratio and pressure factor were studied through orthogonal experiments. Reaction temperature of 230℃,higher ratio of H2/methyl acetate,lower space velocity were beneficial to the reaction,the effect of reaction pressure in the range of investigation was not significant. The highest conversion was up to 0.954,its corresponding selectivity was 0.974,while the highest selectivity was up to 0.989,and its corresponding conversion was 0.920. Gas chromatography at low temperature was used to analyze methanol and ethyl acetate,which were difficult to separate,and achieved perfect baseline separation.关键词
