Selective Oxidation of Ethanol over Supported Gold Catalysts

Abstract

Abstract: The gold catalysts supported on several oxides and H-ZSM-5 were used in the se lective oxidation of ethanol. Au/Al2O3 catalyst gave the highest selectivity for acetic ester. An appropriate quantity of basic additive in the reaction sys tem could evidently increase the ethanol conversion and the selectivity for acet ic ester. The ethanol conversion was 4.7% with 93.5% selectivity for acetic es ter under the optimal conditions.

Key words: deposition-precipitation, gold, alumina, H-ZSM-5 zeolite, silica, titania, magnesia, supported catalyst, ethanol, selective oxidation
