2963.     ---------------.  [RUHRCHEMIE, A.-G.]  [Tests on the Precipitation of Cobalt Catalysts.]  FIAT Reel K-29, no date, frames 6,991-6,994; PB 70,218; TOM Reel 296.

        Description of tests on the precipitation of Co for the preparation of Co catalysts with kieselguhr as carrier material and with the use of a mixture of gaseous NH₃ and CO₂ for the precipitation instead of the usual Na₂CO₃.  It is demonstrated that useful catalysts also can be prepared in this manner.
