710.    ---------------. [DOHSE, H.]  [Catalytic Gas Reactions.]  Chem. Fabrik, vol. 11, 1938, pp. 133-139; Chem. Abs., vol. 32, 1938, p. 4060.

     Gaseous, liquid, and solid catalysts are discussed briefly, with examples to illustrate the reacting materials, temperature pressure, catalyst, and products.  The mechanism of catalysis, catalyst formation, and loss of activity by contraction from overheating and from poisoning are explained.  A flow diagram, 5 views, and a model of a 75,000-ton plant for the manufacture of motor fuel from coal by the Fischer and Tropsch method are shown, and also cuts of apparatus for H₂SO₄ manufacture, including the Lurgi apparatus for direct conversion of H₂S into H₂SO₄.
