X FA1 FAZ 6. Reactors in Series. The operation of a fluidized bed reactor (FBR) can be approximated to an ideal CSTR since the reactant, product, and catalyst undergo a large extent of back- mixing. In a chemical plant, a FBR loaded with 1 Ton of catalyst is processing 10,000 mol/hr of a gaseous feed of pure A to carry out the first-order reaction A+B at a pressure of 10 atm. The feed and reactor temperature was kept at 473 K at all times. Pressure drop in the FBR can be neglected. Under these conditions, only 30% conversion was reached and the plant manager is unhappy because this low conversion makes the process uneconomical. To increase the conversion to 60%, the engineering department has proposed to use two identical FBR in series. How much catalyst should be required in each reactor if all the other conditions (Fo, T, P) are kept unchanged? FA X = 0 FA
