2540. OSTERMEIER, L. [Use of the Residual Gas From the Fischer-Tropsch Gasoline-Synthesis Process as City Gas.] Gas u. Wasserfach, vol. 81, 1938, pp. 52-57; British Chem. Abs., 1938, B, p. 243; Chem. Abs., vol. 32, 1938, p. 3126. High purity of the residual gas from the Fischer-Tropsch process is an important factor in considering its use for city gas, but this is partly balanced by its high content of inerts, especially CO2 and high specific gravity. This gas may be converted into city gas by washing out CO2, preferably with a solution containing a mixture of K and Na carbonate or by detoxification (removal of CO) before removing CO2. In either case the density and inert content will be reduced to permissible limits, and a mixture of treated and untreated gas may be used, with or without other normal manufactured gases. The combination of synthesis-gas manufacture with the use of the residual gas would seem to be favorable for large gas works in Germany. |
