heal.abstract	The catalytic destruction of ethanol (0.5% v/v) over a typical three-way catalyst (Pt/Rh/Ce) and two base catalysts (1% CuO and 10% CuO on gamma-Al2O3) was studied in a continuous flow reactor, under atmospheric pressure. The effect of the temperature (100-500degreesC) and of the oxygen concentration (0-10% v/v) on the operation of the tested catalysts and on the product profiles is presented. The formation of acetaldehyde during the catalytic destruction of ethanol, the main concern of ethanol addition to fuels, was extremely dependent on the oxygen concentration. It is noteworthy that more acetaldehyde was produced during the oxidation of ethanol in oxygen deficit conditions than during its decomposition in the absence of oxygen. Copper addition on gamma-Al2O3 enhanced acetaldehyde formation, while less acetaldehyde amounts were produced over the noble metal catalyst.	en
