Coal - WOU

The products of coalification are divided into four major categories based on the carbon content of the material. It is the carbon content of the coal that supplies most of its heating value. The greater the carbon to oxygen ratio the harder the coal, the more reduced the state of the carbons and the more potential energy it contains.

Coal explained - U.S. Energy Information Administration (EIA)

Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants over time.
