Asphalts are _________________?
Correct answer: C. Readily oxidisable and form carbonaceous sludge
- A. Low molecular weight & low boiling point compounds present in petroleum
- B. Desirable in catalytic cracking feedstock, because they produce coke
- C. Readily oxidisable and form carbonaceous sludge
- D. All A., B. & C.
Explanation
Asphalts are heavy, high-boiling petroleum residues that can oxidise and form carbonaceous sludge. They are undesirable in catalytic-cracking feed because their tendency to form coke deactivates the catalyst.
