Which catalysts are used in catalytic cracking?
Correct answer: B. Silica, alumina
- A. Silica, lime
- B. Silica, alumina
- C. Silica, Soda ash
- D. Alumina,Pt
Explanation
Option B is correct since silica and alumina are used in catalytic cracking to produce smaller more useful fractions from larger hydrocarbons.Option A is incorrect since a mixture of silica and lime is used to make cement.Option C is incorrect since silica and soda ash is used in the process of glass manufacturing.Option D is incorrect since alumina and platinum are used in the process of cyclohexane dehydrogenation.
