3472.     ---------------.  [TSUTSUMI, S.]  Studies of the Promoting Action of a Catalyst Promoter and Carrier.  II.  Jour. Chem. Soc. Japan, vol. 58, 1937, pp. 63-70; Chem. Abs., vol. 31, 1937, p. 2915.

        Effect of the calcining temperature upon the gas-absorbing power of the mixtures Co+Cu+U₃O₈ in the range 200°-300°, and Co+U₃O₈, Co+ThO₂ in the range 250°-450° containing various amounts of diatomaceous earth was studied.  The gas used was the mixture CO+H₂ in the ratio 1:2.  The proper temperature to get the maximum absorbing power does not change much with the amount of the diatomaceous earth.
