Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite. Elemental analysis gives empirical formulas such as C 137 H 97 O 9 NS for bituminous coal and C 240 H 90 O 4 NS for high-grade anthracite. Anthracite coal is a dense, hard rock with a jet-black color and a metallic luster. It contains between 86% and 98%

into different types of coal Source: Kentucky Geological Survey Coal is divided into 4 ranks: (1) Anthracite (2) Bituminous (3) Sub-bituminous lignite or sub-bituminous, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest & Appalachia . CCTR
Role of Coal in Sustainable Energy Development
Coal is divided into four classes: lignite, sub-bituminous, bituminous, and anthracite. Coal has many important uses, but most significantly in electricity generation, steel and cement manufacture, and industrial process heating. In the developing world, the use of coal in the household, for heating and cooking, is important [3].
Nitrogenous Chemicals from Carbon Based Materials
Coal consists mostly of organic carbon as aliphatic and aromatic forms. Coal is divided into four classes: lignite, sub-bituminous, bituminous, and anthracite. Coal has played a key role as a primary source of organic chemicals as well as a primary energy source. Coal may become more important both as an energy source and as the source
What are the types of coal? USGS
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 carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal.
