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.
