Coke Making Process

Coke is produced by igniting bituminous coal under reduced oxygen conditions in oven batteries specially designed for this process. The coking process generates the following main volatiles as byproducts: coke oven gas, tar, ammonium sulfate, benzol, toluol and naphtha. A

History of Coke Mining History Resources Coal Culture

Before the advent of large-scale mining in Jefferson and Indiana counties, coke was manufactured by burning coal in heaps on the ground in such a way that only the outer layer burned, leaving the interior of the pile in a carbonized state.

12.2 Coke Production

The primary purpose of modern coke ovens is the production of quality coke for the iron and steel industry. The recovery of coal chemicals is an economical necessity, as they equal approximately 35 percent of the value of the coal. To produce quality metallurgical coke, a high-temperature carbonization process is used.

What is Coking Coal Aspire Mining Limited

Coke is produced by heating coking coals in a coke oven in a reducing atmosphere. As the temperature of the coal increases, it becomes plastic, fusing together before resolidifying into coke particles. This is known as the caking process.

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.
