Light Cycle Oil (LCO) is a byproduct of the fluid catalytic cracking (FCC) process in petroleum refining, characterized by a higher boiling point than gasoline but lighter than traditional diesel. It serves multiple purposes, including:

• Blending Component: Used to enhance diesel and gasoline formulations.
• Feedstock: Acts as a raw material for further refining into low-sulfur diesel and other valuable products.
• Industrial Applications: Utilized in industrial burners and power generation.

LCO's versatility makes it significant in meeting market demands while optimizing refinery operations.
