Which catalyst is commonly used in the catalytic cracking of heavy hydrocarbons during petroleum refining?
Answer
Nickel
The correct answer is Nickel — Choose the correct catalyst.
Step-by-step solution
- Recall that catalytic cracking breaks large hydrocarbon molecules into smaller ones.
- Identify common catalysts used in this process: platinum, nickel, palladium, etc.
- Recognize that nickel is the most widely used catalyst for heavy hydrocarbon cracking.
- Choose the correct catalyst.
Common mistake: Assuming platinum instead of nickel as the primary catalyst
Concept tested: Catalytic cracking
