 1943.    ---------------.  [KÖLBEL, H.]  [Importance of the Fischer-Tropsch Synthesis for the Production of Domestic Diesel Fuels.  II.]  Brennstoff-Chem., vol. 20, 1939, pp. 365-369; Chem. Abs., vol. 34, 1940, p. 7573.

        Mixtures of Kogasin II with bituminous coal-tar oil, especially tar oils obtained from carbonization processes employing offtake from within the coal charge, and high-pressure hydrogenated oils prepared from coal, coal tar, and coal extracts are discussed.  Depending upon ignition characteristics, 40-55% Kogasin II can be used to make fuel mixtures of 65-85 cetene no. and equal to the petroleum fuels in ignitability, resistance to coke formation, and completeness of combustion.  Unrefined tar oils destroy the storage stability of the mixtures, as well as their motor values.
