558.    CHOULAT, G.  [Residual Gas From Fischer-Tropsch Synthesis as Town’s Gas.]  Gas u. Wasserfach, vol. 83, 1940, pp. 497-499; British Abs., 1948, B, I. p. 64.

                  Composition of the gas varies rather widely, mean values being:  CO₂, 17; CO, 9; CH₄, 33; H₂, 20; N₂, 20; C_nH_m 0.7 volume %.  The calorific value is within the town’s gas range, but the high density and low flame speed render its behavior unsatisfactory unless it is mixed with not less than 2.5 volumes of normal town’s gas.
