2851.     ---------------.  [ROELEN, O.]  [Report on the Most Favorable Ratio in Cobalt-Kieselguhr Catalysts.]  FIAT Reel K-25, May 2, 1938, frames 3,757-3,781; PB 70,216; TOM Reel 292.

        Tests and table show that the ratio of 1:2 is the best in such catalysts.  There is no obvious reason for changing this ratio.  Consideration also is given to catalysts of Th-Co-kieselguhr and Th-Mg.  Numerous tables and graphs.
