Coal Coke

Coal coke is generated by dry distillation of coal.  It has been indispensable fuel for heavy industries such as steam locomotives in the old days and steel industries, since it has a high calorific value during combustion and it can obtain high temperatures.  Coke is inferior to coal in appearance, but it also becomes more porous by discharging volatiles when dry distilled, as a result the purity of carbon increases allowing high temperature combustion.

Petroleum Coke

Petroleum Coke is residue when pyrolyzing heavy asphalt fuel oil.  Since calcined Coke has excellent graphitization properties, it is used as raw materials for electrodes, aluminum electrodes, and abrasives.  The properties of petroleum Coke depend on the used raw materials.  There is a wide variety of low to high sulfur content, and they are used properly according to each application.
