Economic Reasons:
ā¢ Petrol is worth much more per litre than heavy fuel oil
ā¢ Converting low-value products into high-value ones increases profit
ā¢ Refinery can adjust production to match market demand
ā¢ Reduces waste and maximises use of crude oil

Polymer Industry:
ā¢ Ethene ā Poly(ethene) (plastic bags, bottles)
ā¢ Propene ā Poly(propene) (ropes, carpets)
ā¢ Styrene ā Poly(styrene) (packaging, insulation)
ā¢ Alkenes are the raw materials for most plastics

Practice questions for Cracking (HT)
What is cracking in chemistry?
Describe the conditions used in thermal cracking and state the types of product formed.
Quick recall flashcards
Why is cracking needed?
Long alkanes are less useful. Cracking produces shorter alkanes for fuel and alkenes for polymers
What is cracking?
Breaking down long-chain hydrocarbons into shorter, more useful molecules
