What You Should Know About Metallurgical Coal

21.08.  · Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces. Heat and pressure cause physical and chemical changes that result in carbon-rich coal. Metallurgical Coal Metallurgical coal differs from thermal coal, used for energy and heating, by its carbon content and its caking ability. Caking

Coal Carbonization for Coke Production – IspatGuru

Dec 08, · Coal Carbonization for Coke Production. Coal carbonization is the process by which coal is heated and volatile products (liquid and gaseous) are driven off, leaving a solid residue called coke. Carbonization of coal involves heating coal to high temperatures either in the absence of oxygen (O2) or in control quantity of O2.
