How is crude oil made bbc bitesize
Crude oil was made over millions of years from tiny plants and animals, called plankton. The plankton on the left would form oil in about 150 million years time if the sea bed is not disturbed. The plankton on the left would form oil in about 150 million years time if the sea bed is not disturbed. We look at how crude oil is formed and then look at hydrocarbon molecules, specifically the alkanes. We explore the general formula of alkanes and how this is used. Crude oil is a mixture of a very large number of compounds. It is formed from the remains of plants and animals which died millions of years ago. This is why it is called a fossil fuel. Most of the compounds in crude oil consist of molecules made up of hydrogen and carbon atoms only, we call these type of compounds hydrocarbons. Where Next? Fractional Distillation and Cracking.

The main process is fractional distillation. When you see an oil refinery, you will see a number of large vertical cylindrical columns. These are known as distillation columns. Distillation columns separate the different fractions of oil by
Crude oil, coal and gas are fossil fuels. They were formed over millions of years, from the remains of dead organisms: Fossil fuels are non-renewable. They took a very long time to form and we are using them up faster than they can be replaced - once they have all been used up, they cannot be replaced.
Crude oil is a finite resource. Petrol and other fuels are produced from it using fractional distillation. Cracking is used to convert long alkanes into shorter, more useful hydrocarbons. Crude oil is a mixture of hydrocarbons formed from the remains of simple marine organisms over millions of years. Fractional distillation separates a mixture into a number of different parts, called fractions. A fraction of crude oil is a mixture of chemicals in the crude oil that have similar boiling points. Crude oil is a finite resource. Petrol and other fuels are produced from it using fractional distillation. Cracking is used to convert long alkanes into shorter, more useful hydrocarbons. During the fractional distillation of crude oil: heated crude oil enters a tall fractionating column, which is hot at the bottom and gets cooler towards the top. vapours from the oil rise through the column. vapours condense when they become cool enough. liquids are led out of the column at different heights. Crude oil, coal and gas are fossil fuels. They were formed over millions of years, from the remains of dead organisms: Fossil fuels are non-renewable. They took a very long time to form and we are using them up faster than they can be replaced - once they have all been used up, they cannot be replaced. Rocks around them also heated them up. Together the heat and the pressure turned the remains into crude oil. It was important that no air or oxygen was present. Fossil fuels are finite (non-renewable) energy resources. Their supply is limited and they will eventually run out.

Fossil fuels like coal, crude oil and natural gas have been formed over millions of years from dead plant and animal remains which have been buried.
Rocks around them also heated them up. Together the heat and the pressure turned the remains into crude oil. It was important that no air or oxygen was present. Fossil fuels are finite (non-renewable) energy resources. Their supply is limited and they will eventually run out.

Most plastics and synthetic fibres are made from chemicals derived from crude oil and are made up of long chain molecules called polymers.
