Carbon particles accumulated on the catalyst used in the gas oil cracking lies in the category of _____________________ poison?
Correct answer: A. Deposited
- A. Deposited
- B. Chemisorbed
- C. Selectivity
- D. Stability
Explanation
Carbon formed during gas-oil cracking remains deposited on the catalyst surface or inside its pores, so it is classified as a deposited poison. Chemisorbed poisons attach molecularly to active sites without forming such a carbon deposit.
