The catalytic irreversible elementary reaction, A (g) B (g) takes place in an isothermal fixed bed packed with a spherical porous catalyst. Below, the rates of the reaction as a function of inlet total molar flowrate (Fra) and various catalyst and reaction parameters is shown below. 20 400 K, d. 0.03 cm 15 mol g-cates 400 K, d, -0.1 cm 400 K, d = 0.6 cm 400 K, d. - 0.8 cm 10 300 K, C = 0.3 cm 300 K, d, = 0.8 cm = 500 do 150 200 2500 3doo 36.60 do 4560 2360 Fro (mol/s) a. Are there conditions where reaction is limited by external mass transfer? Explain your answer b. If your answer to part (a) was yes, what regions (i.e., conditions, d, T,F) are external mass transfer-limited? c. What regions are reaction rate-limited? d. Are there conditions where reaction is limited by internal diffusion? Explain your answer. e. What region is internal-diffusion-controlled? f. Calculate the internal effectiveness factor at T = 400 K and do = 0.8 cm.
