Coal Processing - an overview ScienceDirect Topics

Aug 09, 1982  Describing and eliminating the health hazards of coal processing requires an understanding of the nature of the raw materials, products, by-products, the type of pollutants produced, the design of the plant and its operating methods (Wadden, 1976).The structure of coal was described in Chapter 6 and is thought to be a highly linked amorphous polymer consisting of aggregates connected

Coke (fuel) - Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from cr
