What are the types of coal? - USGS

There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

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 types - Energy Education

Different coal types are all minerals and rocks made largely of carbon. This fossil fuel generates ~40% of the world's electricity and about 25% of the world's primary energy. However, not all coal used is the same; it comes in different quantity levels of carbon—which dictates the quality of the coal. Higher quality coal produces less smoke, burns longer, and provides more energy than lower ...
