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.

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 imports and exports - U.S. Energy Information ...

Sep 01, 2021  Although the United States produces most of the coal that it consumes, it imports coal to meet some domestic demand. For example, coal-burning power plants along the Gulf Coast and the Atlantic Ocean sometimes find it cheaper to import coal from other countries than to obtain coal from U.S. coal-producing regions.

Coal 101: The 4 Types of Coal and Their Uses Energy Central

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
