Which of the following factors control the deactivation of a porous catalyst pellet?
Correct answer: D. All A., B. and C.
- A. Decay reactions
- B. Pore diffusion
- C. Form of surface attack by poison
- D. All A., B. and C.
Explanation
Pellet deactivation depends on the decay mechanism, resistance to pore diffusion, and how the poison attacks or deposits on the active surface. Therefore, all three listed factors can control deactivation.
