Coke is a grey, hard, and porous coalbased 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.

Coke is used mainly as a reducing agent in the extraction of metals. Question 8. Where do we get coal and how is it formed? Answer: We get coal deep in the earth's crust in coal mines.
WhatsApp: +86 18037808511Destructive distillation ("coking") of coal occurs in coke ovens without contact with air. Most U. S. coke plants use the KopperBecker byproduct oven. These ovens must remain airtight under the cyclic stress of expansion and contraction. Each oven has 3 main parts: coking chambers, heating chambers, and regenerative chambers.

WhatsApp: +86 18037808511Coal tar, a black, sticky liquid thicker than water, is produced when coal is heated in the absence of air, a process called destructive distillation. Much coal tar is produced by the steel industry as it produces millions of tons of coke each year to fuel the furnaces used in separating iron from its ores.
WhatsApp: +86 18037808511Process Description1,2 All metallurgical coke is produced using the "byproduct" method. Destructive distillation ("coking") of coal occurs in coke ovens without contact with air. Most U. S. coke plants use the KopperBecker byproduct oven. These ovens must remain airtight under the cyclic stress of expansion and contraction.
WhatsApp: +86 18037808511Distructive distillation of coal is a process of heating a complex substance coal in limited supply of air so that it breaks down into simplier substances. In this process the coal is heated to 1000 degree celcius in absence of air to obtain different useful components such as coke, coal tar and coal gas. Scholr Boy.
WhatsApp: +86 18037808511Cannel coal of the Pennsylvanian subperiod from NE Ohio used to produce coal oil. Coal oil is a shale oil obtained from the destructive distillation of cannel coal, mineral wax, or bituminous shale, once used widely for illumination.. Chemically similar to the more refined, petroleumderived kerosene, it consists mainly of several hydrocarbons of the alkane series, with 10 to 16 carbon atoms ...
WhatsApp: +86 18037808511When coal is heated strongly in the absence of air, a large number of organic and some inorganic compounds are formed. This process is called destructive distillation of coal. Two products of this process are coal tar and coal gas.

WhatsApp: +86 18037808511This chapter discusses coal carbonization. Coal carbonization involves the destructive distillation of coal, and during this process, as much as 50% of the weight of the coal feedstock is driven off as gaseous and volatile components. These are regarded as byproducts of the coking process, and include combustible gases (for example, methane ...
WhatsApp: +86 18037808511Destructive distillation of coal involves heating coal to high temperatures (about (1000,^circ {rm{C}})) in the absence of air. The process causes its decomposition into different products solid and gaseous. Some of the gases condense while some dissolve in water. Some of the products obtained in the process are coke, coal, coal tar, and ...
WhatsApp: +86 18037808511The chemical process takes place on unprocessed materials. When organic substances are decomposed by heat in the absence of air is known as destructive distillation. Products obtained from the destructive distillation of coal are coal gas and coal tar. Coal is one of the most commonly used natural hydrocarbon substances. It is obtained by mining.
