Question:
Fluid catalytic cracking (FCC) mainly converts:
Fluid catalytic cracking (FCC) mainly converts:
Show Hint
Shortcut: FCC = Heavy oil $\rightarrow$ gasoline + LPG.
Updated On: Jun 9, 2026
- Light naphtha into aromatics
- Heavy gas oil into gasoline and LPG
- Natural gas into olefins
- Residual oil into lubricants
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Fluid catalytic cracking is an important refinery process that breaks large hydrocarbon molecules into smaller valuable fuels.
Step 1:
The common feed to FCC unit is heavy gas oil or similar heavy fractions.
Step 2:
A catalyst helps crack large molecules into shorter hydrocarbon chains.
Step 3:
The process mainly yields gasoline-range hydrocarbons and LPG.
Step 4:
FCC increases fuel value by converting low-value heavy fractions into high-demand fuels.
Step 5:
Hence, FCC mainly converts heavy gas oil into gasoline and LPG.
