Abstract
In this work an alternative process for the obtention of acetaldehyde is presented. It is based on the oxidation of ethyl alcohol over commercial Fe-Mo catalyst. Experimental kinetic data, obtained in an integral reactor, were interpreted by a Temkin's type mechanism, although it is possible to treat the data by a known mechanism similar to the oxidation of methanol to formaldehyde. A new multitubular reactor is then proposed with the obtained rate equation. It is baffled but windowless, so that better temperature control is achieved when compared with conventional reactors. The process considered here exhibits better performance than the best known processes in terms of higher conversions, stability and yield in acetaldehyde.
