999.    FISCHER, F., AND PICHLER, H.  [Preparation of Hydrocarbons From Brown-Coal Coke at 500°.]  Brennstoff-Chem., vol. 8, 1927, pp. 307-309; Ges. Abhandl. Kenntnis Kohle, vol. 8, 1929, pp. 108-114; Chem. Abs., vol. 22, 1928, p. 1458.

      These authors repeat the work of Hoffman and Groll (abs. 1453), which purported to show synthesis of hydrocarbons by passing N2 and steam over activated coke mixed with various metals and metallic oxides as catalyzers.  Hoffman and Groll’s results were not confirmed.
