What is cracking and re - forming?

Cracking is a chemical process used in the petroleum industry to break down larger hydrocarbon molecules into smaller, more useful ones, such as gasoline and diesel. This is typically achieved through methods like thermal cracking and catalytic cracking. Re-forming, on the other hand, involves transforming low-octane hydrocarbons into high-octane fuels by rearranging their molecular structure, often using catalysts. Both processes are essential for optimizing fuel production and meeting energy demands.
