12.2 Coke Production - US EPA
WebPetcoke is over 80% carbon and emits 5% to 10% more carbon dioxide (CO 2) than coal on a per-unit-of-energy basis when it is burned. As petcoke has a higher energy content, petcoke emits between 30% and 80% more CO 2 than coal per unit of weight. [3] Industrial coke furnaces The industrial production of coke from coal is called coking. The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This process vaporises or decomposes organic substances in the … See more Coke is a grey, hard, and porous coal-based 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, … See more Coke can be used as a fuel and as a reducing agent in smelting iron ore in a blast furnace.
