what destructive distillation of iron ore
Destructive distillation . Destructive distillation is a chemical process in which decomposition of unprocessed material is achieved by heating it to a high temperature; the term generally applies to processing of organic material in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents, such as steam or phenols.It is an

what destructive distillation of iron ore. The process of destructive distillation can be viewed as an application of the concept of pyrolysis (the thermal decomposition of certain substances at very high temperatures under relatively inert atmospheres). The process of destructive distillation is known
Destructive Distillation an overview ScienceDirect Topics
Walter Vergara, David Pimentel, in Advances in Energy Systems and Technology, Volume 1, 1978. 2 Pyrolysis. Pyrolysis or destructive distillation is an irreversible chemical change caused by the action of heat in the absence of oxygen (in the presence of oxygen the name of the process is combustion). Without oxygen the energy input splits the chemical bonds and leaves the energy stored.
Destructive distillation and similar topics
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. Important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
12.2 Coke Production US EPA
2021-6-25 Metallurgical coke is used in iron and steel industry processes (primarily in blast furnaces) to reduce iron ore to iron. Over 90 percent of the total coke production is dedicated to blast furnace operations. Foundry coke comprises most of the balance and is used by foundries in furnaces for melting metal and in the preparation of molds.
12.2 Coke Production US EPA
2015-9-10 Most coke plants are co-located with iron and steel production facilities. Coke demand is dependent on the iron and steel industry. This represents a continuing decline from the about 40 plants that were operating in 1987. 12.2.2 Process Description1,2 All metallurgical coke is produced using the "byproduct" method.
