2071. LOHRISCH, W. (J. Pintsch Kom.-Ges.). [Process for the Production of Synthesis Gas.] German Patent 744,244, July 21, 1944; appl. P 84,975, filed Oct. 7, 1942 (Cl. 26 a-18.01). TOM Reel 67, item 75, frames 1,120-1,121; Meyer Transl. PC-S-II, Fischer-Tropsch, vol. 6, chap. 174, 1949, p. 31.

3 CH₄ with 1 CO₂ and 2 H₂O are passed through a heat exchanger to the converter, which is heated to reaction temperature by combustion of another CH₄, and there converted into synthesis gas with proportions of 4 CO:8 H₂. The latter passes through the heat exchanger to storage and gives up its heat to the incoming raw gas mixture. The hot gases from the combustion of the CH₄, after heating the converter, are used to produce the steam for the process and then are scrubbed for the CO₂. The steam and the CO₂ thus produced are combined with the raw CH₄ to begin another cycle.
