Correct answer: A. Gives higher yield of petrol

  • A. Gives higher yield of petrol
  • B. Lower octane number of petrol
  • C. Higher sulphur content in the product
  • D. Higher gum forming material in petrol

Explanation

Catalytic cracking converts heavy petroleum fractions into more gasoline-range products and generally gives a higher gasoline yield than thermal cracking. It also usually produces gasoline with a higher octane number, making option a the relevant comparison.
