Coal to Coke Conversion Process Uses and Benefit of Coal

The process in which conversion of coal to coke takes place is referred to as coal carbonization. Coke is nothing but a carbonaceous material solid in nature which is again derived through the process of destructive distillation of low ash, low-sulfur and bituminous coal. The transformation of coal to coke is better known as the coke-making process.

Coal Carbonization for Coke Production IspatGuru

2018. 12. 8.  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.

Coke Making Process

Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. In the coke oven, the coal is heated to 1,800°F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called “coke” remains.

Carbonization of Coal for Metallurgical Coke Production

2014. 11. 15.  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. Destructive distillation reactions proceed rapidly in the plastic layer with evolution of volatile products.

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

Met coal is heated above 1,000ºC in a coking oven to create coke a hard, porous lump. The coke is then added to a blast furnace with iron ore. Hot air and PCI are introduced, creating a flame temperature over 2,000ºC. The burning coal and coke produces carbon monoxide, which, along with the high temperature, converts the iron ore into a liquid.
