Cracking of Octane (Thermal Cracking)

C8H18 → C4H10 + C4H8

ภาพรวม

Large hydrocarbon molecules like octane are broken down into smaller, more useful molecules through thermal or catalytic cracking. This process is essential in petroleum refining to produce gasoline, ethylene, and other petrochemicals from heavier crude oil fractions.
