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.
