From Peat to Anthracite: Different Types of Coal

Subbituminous coal is lignite coal that has been naturally processed for a longer time period, and also deeper in the ground. This type of coal has a higher energy content, but a lower sulfur content, making it burn more cleanly. The most abundant of the coals, bituminous coal is the third ranking of the coal family.

Bituminous coal - Wikipedia

Bituminous coal, or black coal, is a relatively soft coal containing a tar-like substance called bitumen or asphalt.Its quality is ranked higher than lignite and sub-bituminous coal, but poorer than anthracite.Formation is usually the result of high pressure being exerted on lignite. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright …
