The catalytic decomposition of ozone in fluidized beds of silica particles impregnated with Fe 2 O 3

Question:

The catalytic decomposition of ozone in fluidized beds of silica particles impregnated with Fe2O3 was studied by Van Swaaij and Zuiderweg. The decomposition reaction for a given temperature and catalyst loading was shown to follow a simple first-order model:203 k 30 and k = 1 [s] FeO3

These researchers report the following experimental results:(voidage in emulsion phase) = 0.45 Hbed = 2.4 m Ug = 0.15 m/s (superficial velocity) Umf = 0.01 m/s Ububble

For the case where the interchange coefficient between the bubble and emulsion phase is zero (i.e., gas in bubbles does not interact with the catalyst), determine the conversion of pure ozone feed when the emulsion phase is completely well mixed.
