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 ...

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.
