3078.     ---------------.  [SCHENCK, -----.]  [Reducibility of Cobalt Catalysts.]  FIAT Reel K29, frames 7, 134-7, 135, 1938; PB 70,218; TOM Reel 295.

        It is established by experiments that the reducibility of a constant volume of 3 types of catalysts (Co-Th-, Co-Th-Mg-, and Co-Mg-) decreases with an increasing proportion of kieselguhr, and that, with a kieselguhr proportion of 200, about 3 times the quantity of H₂ is necessary to reduce Th-Mg and Mg catalysts, compared with pure Th catalyst under otherwise equal conditions.  1 diagram.
