摘要：

A kinetic study of the dehydrogenation of ethanol to acetaldehyde on an unsupported catalyst of base composition CuO – Cr2O3 was carried out in an isothermal reactor fed with ethanol 95% vol. in the temperature range 225–285°C with space velocities 1.5–7.5 LHSV at atmospheric pressure. The mechanism which was found suitable to describe the reaction was that of surface adsorption on dual sites. Taking into account interphase and intraphase diffusion, the observed conversions of ethanol were reconstructed with a standard error below 10%, thus confirming the validity of the physical assumptions.
