Chapter 7 COAL - Pennsylvania State University

Coal is an organic rock (as opposed to most other rocks in the earth's crust, such as clays and sandstone, which are inorganic); it contains mostly carbon (C), but it also has hydrogen (H), oxygen (O), sulfur (S) and nitrogen (N), as well as some inorganic constituents (minerals) and water (H2O).

Coke (fuel) - Wikipedia

The industrial production of coke from coal is called coking.The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This process vaporises or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.

Coking coals. Although chemical composition alone cannot be used to predict whether a coal is suitable for coking, prime coking coals generally have volatile matter contents of 20 to 32 percent—i.e., the low- and medium-volatile bituminous ranks. When heated in the absence of air, these coals first become plastic, then undergo decomposition, and finally form coke when the decomposed material ...
