CRUDE OIL AND FUELS

Fuels from crude oil

• Crude oil is a mixture of many different compounds.
• Distillation can be used to separate mixtures of liquids.
• Most of the compounds in crude oil are hydrocarbons-the contain only hydrogen and carbon.
• Alkanes are saturated hydrocarbons. They contain as many hydrogen atoms as possible in their molecules.

Fractional distillation

• Crude oil is separated into fractions using fractional distillation.
• The properties of each fraction depend on the size of the hydrocarbon molecules.
• Fractions with lower boiling points are less viscous and burn more easily.
