It needs to be noted well that coal is a brownish-black or combustible black rudimentary rock formed as rock strata. Coal mainly contains carbon with various other elements such as oxygen, sulphur, hydrogen and nitrogen. When dead matter of plant is decayed, it is known to get converted into coal with much amount of heat. Coal is used primarily as a fuel and is used extensively since industrial revolution. There exist various kinds of by products of coal and we shall discuss few of them herewith: 

1. Smokeless Coal

This product of coal is a type of solid fuel which emits a lot of smoke during combustion. This is manufactured from non volatile materials. They are known to give up much more heat than normal house coal. This product is used cost-effectively as compared to normal house coal. 

2. Coal Tar

This is a kind of thick dark liquid which is a byproduct of goal gas and coke that is manufactured from coal. It has industrial as well as medical applications. This is also used on skin to treat dandruff (seborrheic dermatitis) as well as psoriasis. 

3. Crude Coal Creosot Oil

This by-product of coal is used as a disinfectant, biocide, insecticide as well as fungicide. It is a kind of preservative used in shingles, railroad ties, marine pilings as well as telephone poles. 

4. Coal Tar Distillation

This process is undertaken to produce cresylic acids, anthracene, creosols, naphtha, benzols as well as pyridine. The residue of this process is coal tar pitch and is known to have certain specific physical and chemical properties. 

5. Coke

This is a kind of solid fuel which is made by heating coal when air is absent. This is done so that the volatile components fade off. It is a kind of hard, porous and grey fuel with few impurities and high content of carbon. It is produced by heating coal in the absence of air. 

6. Charcoal

This product of coal is lightweight and is produced by string heating of wood. It is commonly used to treat poisonings. It is also used to treat pregnancy issues, bile flow problems, upset stomach, hangovers, flatulence, high cholesterol levels, and for healing wounds. 

7. Carbon Black

This is a byproduct that is produced ny incomplete combustion of heavy products of petroleum such as vegetable matter, coal tar, ethylene cracking tar, FCC tar, and others. 

8. Briquettes

This by-product of coal is actually a compressed block of coal dust or combustible biomass material (which includes paper, peat, sawdust, wood chips, charcoal and others). 

9. Lignite Coal

This by product of coal is known as brown coal and isbrown and combustible in form. Lignite is being used in fossil fuel power technology. 

10. Coal Tar Pitch

This by product of coal is produced from coal tar. This may be hazardous to environment, especially to aquatic organisms and may depict long term effects. 

11. Non Coking Coal

This by product of coal does not have any caking properties and is used mainly in the process of power generation. It is known to have ash content and is used in many industries such as brick manufacturing, paper industry, chemical industry, glass industry, fertilizer industry as well as ceramic industry.
