CokeMitsubishi™ Coke

Coke (from German "Koks") is manufactured by carbonizing (coking) coal at a high temperature of about 1200 ℃ in a coke oven. Coke is one of the essential raw materials for iron-making in blast furnaces.
Coke mainly consists of carbon.

Mitsubishi Chemical's Sakaide plant has one of the world's largest coke ovens with 323 ovens and produces 3.9 million tons of high-quality coke per year.  Each year, Sakaide plant imports 60-70 different types of coals from various countries.In order to ensure stability, over 10 types of coals are blended.

Iron-making Raw Material
The coke has functions as heat source, reducing agent and spacer in blast furnaces. Because it is more favorable for the oxygen to combine with carbon than with iron, the following change occurs in which oxygen is removed from iron.
