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.
