Coke and Chemistry (v.57, #10) |

The modification of coal's plastic and viscous properties on oxidation is studied. When coal of different ranks undergoes oxidation during open storage in heaps, its plastic and viscous properties—in particular, its plastic-layer thickness y (mm)—change in two stages. In the first, y declines sharply, in both summer and winter. In the second, the decline slows.

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 ...

Coal homogenization - Wikipedia

Coal homogenization refers to the process of mixing coal to reduce the variance of the product supplied. This homogenization process is performed during the coal stockpiling operation. Although the terms blending and homogenization are often used interchangeably, there are differences as the definitions show. The most notable difference is that blending refers to stacking coal from different ...
