6. AICHER. A. A. Catalytic Apparatus Suitable for Exothermic Reactions. United States Patent 2,240,481, May 6, 1941: appl. Filed Nov. 17, 1938. Serial No. 240,992, in Great Britain Nov. 19, 1937: 1 claim (Cl. 23-288). Chem. Abs., vol. 35, 1941, p. 5000.

Use is made of a plurality of reaction units. Each unit includes a catalyzer chamber containing a catalyst and having inlet and outlet openings for the passage of reaction gases therethrough; a casing enclosing the chamber and spaced therefrom to provide a liquid compartment containing a liquid in heat-exchange relationship with the catalyst: an outlet tube opening into a vaporized liquid therefrom and an inlet tube connected to the compartment to return liquid thereto: a tubular element extending into the body of the liquid in heat-exchange relationship therewith, having its upper end opening into the vapor space and its lower end opening into a conduit for withdrawal of liquid condensed in the tube: and a conduit interconnecting the vapor space of each unit whereby vapor may flow from one space to the other upon temperature fluctuations in the several unites.
