What does the word fraction mean when applied to crude oil?

Answer 1

Methane- we use it as natural gas in cooking .

Ethane- mainly used as a catylist to boost reactions. Ethane also can be used as a refrigerant in cryogenic refrigeration systems.

Propane-

Propane is used as a feedstock for the production of base petrochemicals in steam cracking.

Propane is used in some flamethrowers, as the fuel, or as the pressurizing gas.

Some propane becomes a feedstock for propyl alcohol, a common solvent.

Propane is the primary fuel for hot air balloons.

It is used in semiconductor manufacture to deposit silicon carbide.

Propane is mixed with silicone to form a propellant (sold as green gas) which is used to power gas guns used in airsoft combat gaming.

Liquid propane is commonly used in theme parks and in the movie industry as an inexpensive, high-energy fuel for explosions and other special effects.

Butane-

Butane is often added to regular gasoline to boost performance without creating a highly volatile product. Other common uses for butane include refrigeration, heating and fuel for cigarette lighters.

Pentane -a hydrocarbon of the methane series, existing in three liquidisomeric forms.

Also called normal pentane. the most important isomer ofpentane, a colorless, flammable, water-insoluble, very volatileliquid, C 5 H 1 2 , obtained from petroleum by distillation:used chiefly

Hexane -

Nonane- Nonane is a component of fuel. Due to its highly flammable and volatile nature, it is not widely used in other applications as a fuel.

Decane- a hydrocarbon, C 10 H 22 , of the methane series, occurring inseveral isomeric forms

Answer 2

Read about "fractional distillation". It involves separating out the different components of a mixture (in this case crude oil) on the basis of their different boiling points. Crude oil might be separated into 10 (or more) different fractions from heavy tar to medium weight octanes to lightweight butane.

A fraction in chemistry is a quantity collected from a sample or batch of a substance during fractional distillation. A fraction can be defined as a group of chemicals that have similar boiling points.
