Write the types of mineral coal, explain that the use of anthracene coal is more than the bitumen coal. Why?Answer the given question.
Answers
COAL is mainly of following types:-
Peat is the first step in coal formation. Peat is composed of over 60% organic matter; typically, ferns and vegetation found in swamps or bogs.
Bituminous coal is formed as more pressure is applied to lignite coal.
Anthracite coal is a metamorphic rock and is considered the highest grade coal.
the use of anthracene coal is more than the bitumen coal because
Anthracite coal is a higher grade than bituminous coal and is formed under greater pressure and at higher temperatures. Anthracite coal contains more carbon than bituminous coal and less sulfur, making it more desirable. Bituminous coal also contains more moisture than anthracite coal
Answer:
(i) Types of mineral coal -
Mineral coal is of 4 types.
- Antracite
- Bitumen
- Peat
- Lignite
(ii) Anthracene coal is more useful than bitumen coal -
- Anthracene coal has higher percentage of carbon than bitumen coal.
- Combustion of bitumen produces smoke or smell while antracene burns with clear flame.
- Anthracene coal contain less impurities as compared to bitumen coal.
