Peat – This type of coal has less than 40% to 50% of carbon,while the remaining is moisture. …Lignite – This type of coal has 40% – 55% carbon content,which implies that moisture content is lesser than the peat variant. …Bituminous – The carbon content here is 40% to 80%,which means there is very little moisture. …Anthracite – With 80% to 90% carbon content,this type has the maximum carbon content with very little moisture. …

Are all types of coal the same?
However, not all coal used is the same; it comes in different quantity levels of carbon鈥攚hich dictates the quality of the coal. Higher quality coal produces less smoke, burns longer, and provides more energy than lower quality coal. The table below includes the carbon contents, and energy densities of coal.
What is coal made out of?
What are the different types of coal? The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock.
What is the most commonly used type of coal?
This type of coal is the most commonly used, with 30% of coal resources being sub-bituminous. Figure 4. Lump of bituminous coal. Bituminous coal is the second highest quality of coal, with a carbon content that ranges from 76-86%.
