  • 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:

    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.

Thus, the first treesevolved. But bacteria and fungi did not immediately evolve the ability to decompose lignin, so the did not fully decay but became buried under sediment, eventually turning into coal. About 300 million ye

    All types of coal contain fixed carbon, which provides stored energy and varying amounts of moisture, ash, volatile matter, mercury, and sulfur. Because the physical properties and coal quality vary widely, coal-fired power plants must be engineered to accommodate the specific properties of available feedstock and to reduce emissions of pollutants such as sulfur, mercury, and dioxins.
