Catalyst carriers___________________?
Correct answer: C. Provide large surface area with a small amount of active material
- A. Have very high selectivity
- B. Increase the activity of a catalyst
- C. Provide large surface area with a small amount of active material
- D. Inhibit catalyst poisoning
Explanation
A catalyst carrier or support disperses a relatively small amount of active material over a large porous surface. This increases exposed active area, whereas high selectivity and poisoning resistance are not universal properties of carriers.
