2677.     ---------------.  [PICHLER, H.]  Synthesis of Hydrocarbons From Carbon Monoxide and Hydrogen.  Bureau of Mines Special Rept., June 1947, 159 pp.

        Comprehensive review of the development of the Fischer-Tropsch hydrocarbon synthesis at the Kaiser Wilhelm Institut für Kohlenforschung, and of the most-important work connected therewith.  Consideration is given to the historical background; the normal pressure synthesis, its catalysts, and products; medium-pressure synthesis with Co and Fe catalysts and its products; modifications of these processes, such as hot gas recycle, liquid-phase catalyst suspension process, oil recycle; high-pressure synthesis of paraffin with Ru catalysts; isosynthesis in presence of oxide catalysts (ThO₂); and mechanism of the hydrogenation process.
