Flashcards in Fuels From Crude Oil Deck (7)
What is Crude Oil?
Crude Oil is a compound straight from the ground. It is made up of different compounds called hydrocarbons
These can be separated by fractional distillation to create different types of fuels for example Petrol or Diesel
What is fractional distillation?
The process of seperating the different hydrocarbons from crude oil.
This is done by heating crude oil up a tower.
Each hydrocarbon's chain is of different lengths (and different boiling points) and condenses at different heights because of thjd
As the carbon chain increases what becomes higher and what decreases?
As the carbon chain length increases, the boiling point becomes higher. Viscosity also increases
However flammability decreases
What are Hydrocarbons made of?
Hydrocarbons are made of Carbon and Hydrogen *only*
What is the general formula for an *Alkane*?
The general formula for an *Alkane* is:
Cn H2n + 2
Meaning whatever C is, H is it doubled plus 2
What is the general formula for an *Alkene*?
The general formula for an *Alkene* is:
Meaning whatever C is, H is it but doubled
