Question
The irreversible isomerization of n-pentane to i-pentane (A>B) follows an elementary rate law and the gas phase reaction out in mixed flow reactor (MFR). The rate dependent only on n-pentane and the following data was obtained: Table 2 Experimental data for irreversible isomerization of n-pentane to i-pentane 25 12 25 30 7 (s) CAO (mol/dm) CA (mol/dm³) 100 14 29 27 24 200 190 180 170 150 70 50 140 120 110 90 80 40 20 10 a) Using data from Table 2, suggest the best single flow reactor (either CSTR or PFR) for 85% conversion when the feed rate consists of 100 mol/dm3 of n- pentane. Justify your answer. b) If two-reactor scheme to be installed in the system, proposed the best reactor arrangement for the same conversion in (a) that give optimum condition. Justify your answer. Hint: Determine the concentration of reactant between stages at minimum reaction rate.
