An Irreversible First Order Reaction Ar Was Carried Out In An Isothermal Ideal Plug Flow Reactor With 3 9 Mm Diameter 2 (21.86 KiB) Viewed 31 times
An irreversible first-order reaction, AR, was carried out in an isothermal, ideal plug flow reactor with 3.9 mm diameter spherical catalytic particles. The heat of reaction (AH,) is essentially zero and the inlet concentration of A is 1.1 x 10 mol/cm³ for all experiments. The following data was obtained for reaction carried out at 400 °C: Experiment # Space Time (g-s/cm³) 1 2 3 4 0.18 5 0.36 6 0.72 1.08 Conversion of A 0.18 (%) 0.36 50 75 94 98 (a) For the four experiments at 400°C, does the first-order rate equation fit the data? What is the value of apparent reaction rate constant? Two additional experiments were carried out at 400°C and the following data was obtained: Experiment # Space Time Conversion of A Superficial Mass Velocity (g-s/cm³) (g-s/cm²) 0.57 (%) Superficial Mass Velocity (g-s/cm²) 75 0.19 94 0.19 0.19 0.19 0.57
(b) Based on six experiments carried out at 400°C, does the process of external mass transfer have any influence on the performance of the catalysts? Explain your answer and be as quantitative as possible. One additional experiment was carried out at 425°C and the following data was obtained: Experiment # Conversion of A Superficial Mass Velocity (%) (g-s/cm²) 7 Space Time (g-s/cm³) 0.18 54 0.19 (c) Is the result for experimental data at 425 °C consistent with your answer obtained in part (b)? Explain your answer and be as quantitative as possible.
