 1486.    HOOG, H.  Netherland Report on Additional Information on Various Catalytic Processes in Western Germany.  I.  BIOS Misc. Rept. 112, 1947, 50 pp.; PB 96,550.

       Report is made of a trip through the British zone in February 1947, for the purpose of collecting information supplementing previous CIOS and BIOS reports.  Some of the subjects reported are:  (1) Development of the Fischer-Tropsch catalyst (Co-Th-Mg-kieselguhr) by Ruhrchemie A.-G.; preparation of the Fe catalyst with determination of the degree of reduction by the method F+2 FeCl₃→3 FeCl₂ with titration by KMnO₄.  Details are given by Dr. Rottig in an appendix.  (2) status of the Oxo process at Sterkrade-Holten with some description of the reactors and filters and discussions of the catalysts and reaction conditions by Dr. Roelen.  (3) catalytic oxidation of hydrocarbons in the liquid phase at I. G. Farbenindustrie Werke, Uerdingen.  (4) catalytic hydrogenation of various products such as aldol, C₂H₂ to C₂H₄ at Hüls, and methanization of town gas at Ruhrchemie A.-G., Sterkrade-Holten by Dr. Roelen.  (5) manufacture of Fischer-Tropsch cobalt catalyst at Sterkrade-Holten.  (6) compression and storage of water gas, manufacture of CO at I. G. Farbenindustrie A.-G., Leverkusen.  Appendix:  A new method for the determination of the metallic iron in reduced iron catalysts by Dr. Rottig of Ruhrchemie A.-G., Oberhausen-Holten.  Several diagrams of apparatus are shown.
