Longitudinal reactor for chemical syntheses in gas phase and heterogeneous catalysts

摘要

Process and apparatus for carrying out reactions in gas phase, wherein the gas is passed through a cylindrical catalytic reactor so designed that the catalyst bed is divided into several portions arranged in distinct vertical parallelepipedic compartments which are successively traversed by the reaction gas in a direction perpendicular to the axis of the cylindrical reactor. Fresh gas may be supplied between two compartments to maintain the temperature in a well controlled range.
