Transcribed Image Text:

The irreversible gas-phase reaction, AB, is carried out in an isothermal plug-flow reactor packed with solid catalyst particles. The reaction is first-order in the concentration of A at the catalyst particle surface: TA = K CAS. The feed consists of 50% (mole) A and 50% inerts and enters the bed at a temperature of 300 K. The entering volumetric flow rate is 10 L/s. The value of the intrinsic rate constant (k) is 0.80 cm³/s-g.cat. The value of the film-diffusion mass transfer coefficient (k+) is 70.7 cm/s. The specific surface area of the catalyst (a) is 60 cm²/g.cat. Calculate the catalyst weight necessary to achieve 60% conversion of A.
