2071.     ---------------.  [LAUPICHLER, F. G.]  Catalytic Water-Gas Reaction – Mass Transfer and Catalyst Activity.  Ind. Eng. Chem., vol. 30, 1938, pp. 578-586; British Chem. Abs., vol. 32, 1938, p. 4866.

        Equations are derived for mass transfer and reaction velocity in the catalytic water-gas reaction at constant temperature, which permit calculation of conversion rate for any given amount of catalyst, or the amount of catalyst required to obtain a given conversion.  The equations are then extended to include the effect of gradually increasing temperature as found in commercial processes.  The heterogeneous velocity coefficient obtained may be used to compare the activities of different catalysts.  The effect of varying the initial temperature, steam:CO ratio, and flow rate were determined.  The equations gave calculated values in good agreement with experimental determinations and are useful in determining the optimum conditions for operating catalytic converters.
