Using a catalyst or using steam
Cracking can be performed in several ways, but two of the main methods include using a catalyst or using steam. These are called catalytic cracking and steam cracking. Both cracking methods involve heat. During cracking, the hydrocarbons are heated up in order for them to break down.
