Cracking Hydrocarbons Flashcards
1
Q
Why crack hydrocarbons
A
Long hydrocarbons high boiling points viscous
Shorts lower boiling point finer and paler
Demand for short chain is is much higher
As more useful
Also produces alkenes used to make polymers
2
Q
What is cracking
A
Splitting up long chain hydrocarbons
It is a form of thermal decomposition
3
Q

4
Q
