The elementary irreversible gas-phase catalytic reaction is to be carried out in a moving-bed reactor at constant temperature. The reactor contains 5 kg of catalyst. The feed is stoichiometric in A and B. The entering concentration of A is 0.2 mol/dm3. The catalyst decay law is zero order with kD = 0.2 s–1 and k = 1.0 dm6/(mol⋅kg-cat⋅s) and the volumetric flow rate is υ0 = 1 dm3/s. (a) What conversion will be achieved for a catalyst feed rate of 0.5 kg/s? (c) What is the maximum conversion that could be achieved (i.e., at an infinite catalyst loading rate)? (d) What catalyst loading rate is necessary to achieve 40% conversion? (e) At what catalyst loading rate (kg/s) will the catalyst activity be exactly zero at the exit of the reactor?
