Facts |
Mixture of hydrocarbons Split using fractional distillation |
|
|
Fractional Distillation |
1) Oil pumped into bottom 2) Heated and evaporates 3) Vaporised oil rises in column 4) Condenses at different levels, tapped off |
|
|
Properties |
Mostly alkanes, chains of carbon atoms surrounded by hydrogen atoms Different lengths First four= Methane, Ethane, Propane, Butane Alkanes= CnH2n+2 Shorter molecules, more runny hydrocarbon, more volatile(turns into gas easier), more flammable |
|
|
Crude Oil as Fuel |
Used in transportation Generate electricity Non-renewable Burn for energy,carbon dioxide released |
|
|
Cracking |
Splitting up Long-chain Hydrocarbons Do it by passing over powdered catalyst at 400-700 degrees, catalyst is Aluminium Oxide Cracking Alkanes makes Alkenes |
