Coal is a fossil fuel formed from the remains of plants that lived and died millions of years ago. It has been an energy source for centuries and has various associated products. Coal Products generate heat, industrial power generators, make cast iron, and more. Coke, tar, and coal gas are all byproducts of coal processing.
In this Chemistry article, learn about the different types of coal products. Also, learn about the by products of coal and their uses in different industries.
What is Coal?
Coal is a combustible rock made primarily of carbon. It is dark brown or black in appearance. Coal is a fossil fuel formed due to the processing of sedimentary rocks and their decomposition.
Therefore, coal was created after millions of years of extreme heat and pressure.

Coal Production is the process of extracting coal from coal mines and deposits.
A general overview of coal production is as follows:
- Exploration of Coal Deposits.
- Mine Planning and Development.
- Mining of Coal. This step is the initial step towards coal production.
- Once the coal is extracted, it undergoes processing.
- Coal processing involves the removal of impurities.
- After processing, few coal products are obtained. These coal products are transferred to different industrial plants for their uses.
- The utilisation of coal products.

Coal is used for the formation of many products. A variety of coal products are used in many industries. The use of by products of coal depend on their carbon and ash content.
Learn about Coke, Coal Tar and Coal Gas.
Coke is the solid by product of coal. It has poor combustion or destructive distillation property in an enclosed space. It is primarily made of carbon and utilised as a fuel in metallurgy to convert metallic oxides to metals.
Characteristics of Coke
- Coke is one of the purest forms of carbon and is black.
- It is tough and porous
- In the absence of air, heat the coal to produce coke.
Uses of Coke
- Coke is a by product of coal used in steel production.
- While extracting metal, it is used as a reducing agent.
- It is also used as a fuel.
Also, learn about the difference between Methanol and Ethanol here.
Coal is a coal product used to manufacture coal gas and coke.
It is a solid fuel with a high carbon content.
To make refined chemicals and coal products like creosote and coal-tar pitch are used.
Coal tar is categorised as keratoplastic.
Coal Tar Products:
The following are the various Coal Tar Products:
- Coal Tar Pitch
- Coal tar synthetic dyes and pigments
- Derivatives of coal tar products are present in medicinal and herbal products
- Derivatives of coal products are used in marine
Uses of Coal Tar
- It is used in pavement and roofing materials.
- Coal tar is used in the preservation of wood.
- It is used in the manufacturing of synthetic dyes.
- Coal tar is a type of coal in energy production.
Also, learn about Carbonate Ores here.
- A combination of gases, including hydrogen, methane, carbon monoxide, and volatile hydrocarbons.
- The destructive distillation of coal obtains it.
- It is a combustible gas produced from coal delivered by a piping system.
- This coal product is produced without the presence of air.
- It is used in lighting and heating and as an illuminant.

How is Coal Formed? Coal is fossil fuel or fuel that comes from the remains of prehistoric plants or animals. The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into carbon-rich coal under very high temperature and pressure.
