A high carbon content solid residue from an oil refinery process, which can be used as a boiler fuel to produce steam and electric power
In general, coke is made from bituminous coal from which the volatile constituents are driven off by baking in an oven at temperatures as high as 2,000 degrees Fahrenheit, so that the fixed carbon and ash are fused together Coke is hard and porous and is strong enough to support a load of iron ore in a blast furnace It is used both as a fuel and a reducing agent in smelting iron ore in a blast furnace
Coke is the residue formed when coal is heated in the absence of air It is primarily carbon with mineral matter and some residual volatile material (1)
Carbonizing coal made in oven by driving off volatile elements It is a hard porous substance that is principally pure carbon In blast furnaces, coke helps generate the 3000 F temperatures and reducing gases needs to smelt iron ore
clean, light fuel produced when coal is strongly heated in an air- tight oven Coke contains 90% carbon and makes an useful domestic and industrial fuel (used, for example in the iron and steel industries and in the production of town gas)
Mineral coal charred, or depriver of its bitumen, sulphur, or other volatile matter by roasting in a kiln or oven, or by distillation, as in gas works
Coal from which most gases have been removed by heating It burns with intense heat and little smoke, and is used as an industrial fuel A solid residue left after the distillation of petroleum or other liquid hydrocarbons
