using fractional distillation. first crude oil is heated up until it turned to gas and the residue (bitumen) goes through the most bottom pipe to be used for tar macing roads. The fractionating column has different fraction that are at different temperatures (gets colder as you go up). And because hydrocarbons got different boiling point (the longer the hydrocarbon, the higher the boiling point), the gas then travels up and as certain hydrocarbons got to the fraction below their boiling point they turn from gas to liquid and go through the pipe to be used.
The fractional distillation goes in this order:-
(shortest chain/lowest boiling point)
LPG
Petrol
Paraffin
Light Gas Oil
Diesel
Lubricating Substances
Bitumen
(longest chain/highest boiling point)
Hope this help! (if not don't blame me, I'm only 14!)

What are Hydrocarbon molecules are generally what?
Molecules only made up of hydogen and carbon atoms, for example Ethane.
How crude oil is separated into useful fraction?
Crude oil is separated into different substances with similar boiling points. The substances in crude oil can be separated using fractional distillation. The crude oil is evaporated and its vapours are allowed to condense at different temperatures in the fractionating column. Each fraction contains hydrocarbon molecules with a similar number of carbon atoms
What is a molecule containing only carbon and hydrogen called?
A hydrocarbon.
Which carbohydrates are molecules?
Carbohydrates molecules are made of carbon, hydrogen, and oxygen. If it had only carbon and hydrogen (and no oxygen) it would be called a hydrocarbon.
Do hydrocarbon molecules always contain hydrogen carbon and oxygen atoms?
No.Hydrocarbon molecules contain hydrogen and carbon atoms.It is carbohydrate molecules that contain hydrogen, carbon, and oxygen atoms.
Does longer hydrocarbon molecules have higher boiling points than short hydrocarbon molecules?
yes
What small hydrocarbon molecules form polymers?
Monomers are small hydrocarbon molecules that form polymers.
What are two types of detergent molecule?
The most probable type of a molecules in the detergents is the hydrocarbon molecules and the sodium molecules. The sodium molecules binds to water while the hydrocarbon molecule binds to grease.
What is achieved in the process of cracking?
For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
What is the biggest hydrocarbon?
Amino acids are the largest hydrocarbon molecules. However on our planet they are able to link to each other and form protein molecules.
What fuel can be separated from water molecules?
Hydrogen can be separated from water molecules :)
What elements are present in hydrocarbon molecules?
Carbon and Hydrogen
Do short hydrocarbon molecules flow easily?
yes
When the carbon atoms in hydrocarbon molecules are bonded to as many hydrogen atoms as possible is an unsaturated hydrocarbon is produced?
False
Are short hydrocarbon molecules volatile?
Short-chain hydrocarbon molecules excluding methane and ethane are considered to be volatile organic compounds. Generally this is defined as the range from propane to octane,
Why is hydrocarbon important?
it makes smaller molecules which is more useful.
What are Hydrocarbon molecules are generally what?
Molecules only made up of hydogen and carbon atoms, for example Ethane.
