2037.     ---------------.  [LAHIRI, A.]  Synthetic Oil From Coal.  II.  Fischer-Tropsch Process.  Jour. Sci. Ind. Research (India), vol. 7, A, 1948, pp. 406-411; British Abs., 1949, B, I, p. 233.

        Reviews development of the process and discusses inherent advantages and difficulties.  Analyzes recent developments, which have been concentrated on the problem of heat transfer.  Catalysts are now introduced at a constant rate in the fluidized condition and plans contain internal heat exchangers.  Heat of reaction is removed by evaporating oil introduced with the synthesis gas.  The gasification of coal and coke by the Bubiag-Didier, the Thyssen-Galocsy, and the Pintsch-Hillebrand processes are summarized.
