 1971.    KOTZSCHMAR, -----.  [Production of Paraffin From Carbon Monoxide and Hydrogen.  Experiments to Explain the Unfavorable Outcome of a Large-Scale Experiment at Leuna.]  FIAT Reel R-20, frames 7552-7561, Oct. 20, 1939; PB 73,564.

        Experiments were carried out in the I. G. Farbenindustrie Ammonia Laboratory, Oppau, in an attempt to explain the failure of a large-scale experiment at Leuna on the production of paraffin from CO and H₂ in the presence of a Co catalyst.  After elimination of several possible factors, it was concluded that the conditions of reduction of the catalyst were responsible for the failure of the Leuna experiment.  The failure was due to the swift rise in the reduction temperature of the catalyst.  Heating for 4 hr. yielded satisfactory catalysts, whereas heating for 15 min. gave poor catalysts.
