2338.     ---------------.  [MÜLLER, F.]  [Hard-Coal Processing Development.]  Glückauf, vol. 75, No. 33, 1939, pp. 706-711; Coke Smokeless-Fuel Age, vol. 2, 1940, p. 70.

        Paper presented before the Verein bergbaulichen Interessen discusses the technology and operation of the German byproduct coking industry combined with the production of metallurgical coke, the low-temperature carbonization of hard coal and the production of semicoke, the preparation of coal for coking and chemical treatment, the liquefaction of coal, and the advantages of the Fischer-Tropsch process for producing a wide range of synthetic products from coal, coke, semicoke, or coke-oven gas.  It is emphasized the best results are secured by combining the process with low-temperature rather than high-temperature carbonization of hard coal.
