Abstract: The catalyst bed is supported on a downward dished support, which avoids crack formation and channelling due to a temp. fluctuations. Underneath the bed, separated by a distance of less than a tenth of the gas velocity per second, the reaction products pass into the cooler. Prompt quenching improves the yield. Can be used for aldehyde mfe.
