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. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

Incorporating coal as a filler to fabricate polymer composites or as a modifier to enhance the properties of polymeric materials is an important strategy to extend the nonenergy application and sustainability of coal. The literature shows that different process pathways can be used to develop coal/polymer composites owing to different enduses.
