What are the types of coal? - USGS

What are the types of coal? 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.

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.

Apr 27, 2016  Coal is a fossil fuel that is, essentially, “the altered remains of prehistoric vegetation,” as the World Coal Association (WCA) puts it. However, there are a number of different coal types. Coal originally began to form during the Carboniferous period, which took place between 360 and 290 million years ago. Put simply, plant matter accumulated in swamps and peat bogs, and

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 ...

Different Types of Coal. It is important to be aware that "coal" can cover a variety of finished products of differing values and requiring different treatment. The main division is between "coking" coal and "energy or steaming" coal. Coking coals, used to make coke for use in blast furnaces, have particular properties which allow it to form a ...

Each type has different proportions of carbon and thus, have different uses. Peat - This type of coal has less than 40% to 50% of carbon, while the remaining is moisture. This makes it difficult for us to ignite and cannot be easily used. Lignite - This type of coal has 40% - 55% carbon content, which implies that moisture content is lesser ...
