Coal classification Coal is classified into three types as follows, even there is no clear demarcation between them: 1. Anthracite 2. Bituminous 3. Lignite. The Coal is further classified as semi-anthracite, semi-bituminous and sub-bituminous. the anthracite is the oldest coal from a geological perspective.

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 standards presented below were collected by members of the ISO TC 285 Fuels Task Group. These standards were identified as potentially pertaining to the work being conducted by ISO TC 285.

The materials specifically covered by these standards can be in the form of lump coke, pulverized coal, bituminous coal, coke and coal ash, reformed gas, and polishing and etching coal. These standards also include the thermophysical property tables for methane, ethane, propane, normal butane, and isobutane.

What are the different types of coal? PDF version. 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.
