What are the different types of coal? | American

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. This process takes millions of years. Types, or “ranks,” of coal are determined by carbon content.

Coal Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

The coal type is an important factor for reducing Hg T in a cs-ESP. The reduction in Hg T in the cs-ESP of sub-bituminous coal- and lignite-burning plants is −4% to 12%, and Hg 0 concentrations emitted into the atmosphere are higher than from those that burn bituminous coals. The Cl content in coal is an important factor affecting the distribution of mercury species.
