摘要:
The invention relates to a process and to an apparatus for effecting chemical syntheses in gaseous phase, under pressure, in the presence of a solid catalyst, for instance for ammonia synthesis from hydrogen and nitrogen or for the synthesis of methanol or higher homolog alcohols from hydrogen and at least one carbon oxide.The reactor of substantially cylindrical shape contains a plurality of elongate compartments of parallelipiped shape, adjacent to each other, the adjacent walls of the compartments or the common walls of the adjacent compartments being gas-tight walls, said tight walls forming hollow plates wherein are provided channels for the flow of a fluid heat carrier flowing through said walls under a pressure substantially equal to the pressure to which are subjected the reaction gases.

The invention relates to a process and to an apparatus for effecting chemical syntheses in gaseous phase, under pressure, in the presence of a solid catalyst, for instance, for ammonia synthesis from hydrogen and nitrogen or for the synthesis of methanol or higher homolog alcohols from hydrogen and at least one carbon oxide.The reactor (8) of substantially cylindrical shape, (see FIG. 4) contains a plurality of elongate compartments (9) of parallelipiped shape, adjacent to each other, the adjacent walls of the compartments or the common walls of the adjacent compartments being gas-tight walls (1), said tight walls forming hollow plates wherein are provided channels for the flow of a fluid heat carrier flowing through said walls under a pressure substantially equal to the pressure to which are subjected the reaction gases.
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.
