HideShow resource information
What do you call the process where long hydrocarbon chains are broken down to form shorter ones?
Cracking
1 of 6
What is the problem with long hydrocarbon chains?
They are not efficient because they do not flow easily and are difficult to ignite.
2 of 6
Explain what happens in CRACKING
The fractions contains the long hydrocarbon chains are heated to vaporise them.
3 of 6
Name the different processes in cracking after vapourisation
Passing over a catalyst/Mixed with steam and heated to very high temperatures
4 of 6
What does cracking do?
Breaks the chemical bonds in the molecules, causing a thermal decomposition reaction.
