562. CHRISTIE, J. J. German Chemicals Industry – Fischer-Tropsch Plants. Chem. Eng., vol. 57, No. 11, 1950, pp. 164-165. Western Germany’s 6 Fischer-Tropsch plants were removed from the reparations list for utilization of processes acceptable to the Allied Military Security Board. Already under way is the conversion of the Krupp-Tribestoffwerk at Wanne-Eickel to the Oxyl process. Work is being done by Lurgi in collaboration with Ruhrchemie A.-G. and is expected to be completed in the spring of 1951. It will have an output of 30,000 tons of alcohols per yr. The Oxyl synthesis (not to be confused with the Oxo process) is applied mainly to obtaining, in addition to hydrocarbons, alcohols with 2-40 C atoms. Alcohols and neutral oils are worked up and separated to yield primary alcohols with a purity of 95-98%, suitable for use as solvents or softeners or further processed into detergents. The synthesis gas used as the basic material differs from that used in the Fischer-Tropsch synthesis. Two catalysts are used: A ferrous-based catalyst in the gaseous-reaction phase, and a Co-based catalyst in the liquid phase. The final products include approximately 17% gasoline, oils, and lubricants. It is proposed to convert the Bergkamen plant of Essener Steinkohlen A.-G. to production of gas for normal heating purposes by hyper-purification and detoxification of coke-oven gases. Proposals for conversion or disposition of the other 4 Fischer-Tropsch plants have not been announced. These plants are: Ruhrchemie A.-G. at Oberhausen-Holten, capacity 65,000 tons per year; Steinkohlenberg werk Rheinpreussen at Moers, 73,000 tons capacity; Dortmunder Paraffin Werke of Dortmund, 50,000 tons capacity; Gewerkschaft Viktor at Castrop-Rauxel, 61,000 tons capacity.
