        Plant to use the Oxo process was virtually completed at the Fischer-Tropsch installation at Holten when the war ended.  This plant was to treat C₁₂-C₁₇ olefins, converting them first to aldehydes by passing them, together with S-free water containing 39 parts of CO to 45 parts of H₂ over the ordinary Fischer-Tropsch catalyst, the temperature in the 1^st stage being 135° and the pressure 150 atm., the temperatures being controlled by means of steam pressure.  The process was intermittent, each cycle taking 20 min.  The Fischer-Tropsch catalyst consisted of 100 parts Co; 5, Th; 8, Mg; and 180-200, kieselguhr.  A suggested Fe catalyst was to consist of 100 parts Fe; 2.5-4, Cu; 10, lime; and 15, Kieselguhr; it was made from nitrates by precipitation with CO₂.  The aldehydes after distillation were then passed together with pure H₂ over a Ni catalyst to convert them into alcohols.  The temperature was 180° and the pressure the same as for the 1^st reaction.  The alcohols were to be used for making sulfonic soaps.  The development work included the dehydrogenation of C₁₆-C₁₈ cuts from Fischer-Tropsch operations to olefins for use in the Oxo process.  The catalyst in this case was ThO₂ and Cr₂O₃.  Describes method of preparing this catalyst.
