Of Processing Of Coal Into Coke

COAL EXTRACTION AND PROCESSING - WordPress.com

called coke. Coke is coal that has been placed in a coking oven to remove all parts of the coal that is not carbon. When coke burns it creates the high temperature and chemical reaction necessary to turn iron or into raw iron. Raw iron is the key raw material used in the steelmaking process and coal is necessary to create it. Along with steel, coal has used over the centuries for many

Carbonization of Coal for Metallurgical Coke

15.11.2014· This carbonization produces hard coke and is normally employed for the production of metallurgical coke from coking coals. Process of carbonization of coal. The coal to coke transformation takes place as the coal is heated. When the state of fusing is reached, the layer of heated coal softens and fuses. From about 375 deg C to 475 deg C, the coal decomposes to form plastic layer.

Steelmaking: The Coke Oven By-Product Plant

the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke oven gas. After leaving the coke oven chambers, the raw coke oven gas is cooled which results in a liquid condensate stream and a gas stream. The functions of the by-product plant are to take

Coal Carbonization for Coke Production –

08.12.2018· In the process of coke making in the non-recovery ovens, volatiles evolved during coal carbonization are not recovered as by-products but are burned in the oven itself in the presence of controlled quantity of air and the heat of the volatiles of evolving gases is utilized for coking of the coal mass into coke and thus no external heating is needed. The higher level of heat importantly is used

Chemicals from Coal Coking - DIGITAL.CSIC: Home

The history of the chemicals derived from coal is intimately linked to the conversion of coal into coke. This transformation yields, in addition to coke, a series of by-products from which a wide variety of aromatic chemicals can be obtained3,4,5,6,7. A patent for making pitch and tar from coal was taken out in 1681 and coal distillation took off in the following years. By 1781 the Earl of

Metallurgical Coke - an overview | ScienceDirect

W. Rohde, P. Arendt, in 1991 International Conference on Coal Science Proceedings, 1991 1 INTRODUCTION. Metallurgical coke is an important raw material for pig iron production in the blast furnace. During this process the coke undergoes severe mechanical, thermal and chemical stresses. One of these is the CO 2-gasification which may lead to a decisive mechanical weakening of the lump coke
