Abstract: Cooler for reactor as in BE 729336 has finned tubes in parallel arrangement through which coolant is passed, and which serve as support for metal catalyst support. Pref. several rows of tubes are used, the top one being of finned tubes, and other rows being of smooth tubes of dia. >=20% less.

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.
