Anthracite (hard coal) contain 92-98% carbon.
Bituminous (house hold coal) contain 60-80% carbon.
Lignite (soft coal) contain 30-40% carbon.
Peat - this is the most inferior quality of coal.

Peat is formed from the Bryophyta known as Sphagnum which is an aquatic bryophyta and since bryophytes are the earlier known land plants and they form a soft black or brown depositions in damp areas where they grows and with the age they got decayed and form peat hence the Sphagnum is also known as "Peat Moss"
