Publications News 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 carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal.

The biocoal produced under optimized conditions was characterized by 59% of fixed carbon and 41% of volatiles on a dry and ashfree basis, which is similar to bituminous coal. The promising results of dry carbonization producing biocoal similar to bituminous coal could promote this technology, avoiding the necessity of hydrothermal carbonization.

Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite. These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal. Coals other constituents include hydrogen, oxygen, nitrogen, ash, and sulfur. Some of the undesirable chemical constituents include chlorine and sodium.
