Coke is a product of destructive distillation of coal. This is done in an airless furnace or oven ( kiln) at temperatures as high as 2,000 C (3,600 F) but usually around 1,000–1,100 C (1,800–2,000 F). [1] This baking drives off volatile parts of the coal, such as water, gas, and tar . Coke is an almost pure form of carbon.
