Repeat Example 26.4 if the gas is assumed to pass in plug flow through the reactor.

Example 26.4

In a gas-phase environment, particles of B are converted to solid product as follows:

Reaction proceeds according to the shrinking core model with reaction control and with time for complete conversion of particles of 1 hr. A fluidized bed is to be designed to treat 1 ton/hr of solids to 90% conversion using a stoichiometric feed rate of A, fed at C_A0. Find the weight of solids in

the reactor if gas is assumed to be in mixed flow. Note that the gas in the reactor is not at C_A0. Figure E26.4 sketches this problem.
