2107.     LEWIS, W. K.  Replaceability of Natural Gas.  Gas Age, vol. 98, No. 5, 1946, pp. 29-30; 62, 64.

        Emphasizes significance of the possibility of generating both gas and oil from coal by synthetic means.  The complete replaceability of natural gas by synthesis gas at a cost that might easily be brought below the delivered cost of natural gas in many areas of the country is thought to be perfectly feasible.  it is the opinion that it is not unreasonable to look for considerable commercial development of these synthesis processes within the next 10 yr.  The production of synthetic natural gas from coal by the Bergius and Fischer-Tropsch processes is in no sense economically out of the question in the not distant future.
