how are hydrocarbons cracked
how are hydrocarbons cracked
Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are heated to vaporise them. They are then either:
- - passed over a hot catalyst, or
- - mixed with steam and heated to a very high temperature.
