3949.  WIRTH, ---. (I. G. Farbenindustrie A. G.). [Tubular Chamber for Conducting Chemical Conversions.] German Patent Appl. ---, OZ 13,712, filed Oct. 13, 1942. TOM Reel 19, item 149, frames 1,722-1,730; Meyer Transl. PC-S-II, Fischer-Tropsch, vol. 3, 1948, chap. 119, p. 40.

Describes apparatus with diagram for carrying out exothermic or endothermic chemical reactions, such as the catalytic conversion of CO with H₂ to multibranched hydrocarbons, and liquid and solid oxygenated compounds, which require special measures for the removal or introduction of heat. The apparatus is characterized by the use of horizontal or slightly inclined tubes, through which flows a liquid or gaseous cooling or heating agent. The reaction chamber is supported on only 1 side, and the tube bundle so formed and reinforced that it is able to carry its own weight. The cooling or the heating agent, the raw, untreated material, and the reaction products are all conveyed to the supported side of the chamber. The jacket around the reaction chamber is so arranged that it is freely removable from the supported part of the chamber.
