1220a. ---------------. [GORDON, A. S.] Reaction Between Methane and Steam in the Temperature Region 1,000°-1,100°. Ind. Eng. Chem., vol. 44, 1952, pp. 1857-1859; Chem. Abs., vol. 46, 1952, p. 11,637. The present work is an outgrowth of a study of the uncatalyzed steam-natural gas reaction at temperatures 1,200°-1,500° and a total pressure of 1 atmosphere. Between 1,000°-1,100° and 1 atmosphere the results of this work show that the reaction between CH4 and steam is probably a combination of the decomposition of CH4 followed by the steam-carbon reaction. Until C is formed as a result of the decomposition, steam behaves as an inert gas. Production of synthesis gas from CH4 and steam for the Fischer-Tropsch process proceeds smoothly at about 900° on a Ni catalyst. Without an efficient catalyst, at considerably higher temperatures, there is no problem of decomposing CH4, but gasification of the resulting C is so slow that an efficient catalyst for this reaction would be required to make the reaction economically feasible. |
