3900. WENZEL, ---, AND WINTZER, ---. (I. G. Farbenindustrie A. G.). [Removing the Heat of Conversion.] German Patent Appl I 71,916, OZ 13,345, filed Mar. 14, 1942(Cl. IV d-12 o). FIAT Reel 172, frame 289; PB 25,616; TOM Reel 19, item 140, frames 1,640-1,646; Meyer Transl. PC-S-II, Fischer-Tropsch, vol. 2, 1948, chap. 99, p. 74.

Cooling of the converter by the faster removal of the excess heat of conversion by methods other than by H₂O –cooled tubes in the catalyst bed or by wetting the catalyst bed is discussed. The methods suggested depend mainly on variations in gas circulation or in H₂O cooling.
