Question:

Exercise 4.4: Catalyst deactivation in a batch reactor Consider the irreversible, liquid-phase isomerization reaction carried out in a solvent containing dissolved catalyst at 25°C in a batch reactor Aka B The apparent first-order reaction-rate constant, ka, decreases with time because of cat- alyst deterioration. A chemist colleague of yours has studied the catalyst deactivation process and has proposed that it can be modeled by ka= Tt kat in which k is the fresh catalyst rate constant and ka is the deactivation-rate constant. (a) Write down the mole balance for this reactor. (b) Solve the mole balance for ca(t). Sketch your solution. (c) If it takes two hours to reach 50% conversion and the fresh catalyst has a rate 1 constant of 0.6 hr-1, what is ka? (d) How long does it take to reach 75% conversion?
