3136.     ---------------.  [SCHUSTER, F.]  [Production of Standard Public-Utility Gases From Combustible Industrial Gases.]  Gas- u. Wasserfach, vol. 85, 1942, pp. 174-177; Chem. Abs., vol. 37, 1943, p. 3907.

        Discussion of the possibility of changing the composition of typical combustible gases, for example, gas from the low-temperature carbonization of coal, residual gas from the Fischer-Tropsch process, and sewage gas, to that of town gas or coke-oven gas by addition of water gas having a suitable CO:H₂ ratio.  Theoretical examples are worked out.
