In the fluid catalytic cracker (FCC), the cracking reaction is _____________ (i) and the regeneration is _______________ (ii) _______________?
Correct answer: D. (i) endothermic (ii) exothermic
- A. (i) exothermic (ii) endothermic
- B. (i) exothermic (ii) exothermic
- C. (i) endothermic (ii) endothermic
- D. (i) endothermic (ii) exothermic
Explanation
Catalytic cracking consumes heat, so it is endothermic, while burning the deposited coke during catalyst regeneration releases heat and is exothermic. This gives the combination endothermic followed by exothermic.
