A solid carbonaceous residue derived from low-ash, low-sulfur 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 residual ash are fused together. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Coke from coal is grey, hard, and porous and has a heating value of 24.8 million Btu per ton.
Coal that has been processed to remove the impurities. In a coal forge, the coal must be partially burned (to produce coke) before the fire will burn cleanly. Coke can be purchased (in some locations) to make a hotter, cleaner fire than can usually be made with coal.
A form of carbonized coal burned in blast furnaces to reduce iron ore pellets or other iron-bearing materials to molten iron.
The solid carbonaceous residue produced by the thermal decomposition of coal. It is used both as a fuel and as a reducing agent in smelting iron ore in a blast furnace.
A porous, bray infusible product resulting from the dry distillation of bituminous coal, petroleum or coal tar pitch, which drives off most of the volatile matter. Used as a fuel in cupola melting.
Coal from which most of the gases have been removed by heating. This industrial type fuel burns with little smoke and intense heat.
Solid material left after heating coal
coal or petroleum that has been heated to remove the volatile substances, it burns releasing intense heat and is used as an industrial fuel and as a raw material in industrial chemical synthesis.
carbon fuel produced by distillation of coal
become coke; "petroleum oils coke after distillation"
A form of carbon which is more pure than the form in which is usually found, i.e. coal. It is formed by heating lumps of coal in the absence of air in order to drive off the impurities.
purified form of coal and was used in metallurgic applications to make pig iron and steel
A solid carbon product produced by thermal cracking.
a solid material similar to coal that can be produced from processing of heavy oil.
In catalysis, refers to a carbon-rich deposit that can form on the surface, often blocking access to active sites.
Bituminous coal from which the volatile constituents have been driven off by heat, so that the fixed carbon and the ash are fused together.
Coke is a solid carbon fuel and carbon source used to melt and reduce iron ore
Material derived from heating bituminous coal in the absence of air and driving off the volatile constituents, so that the fixed carbon and ash are fused together.
Coke is made from coal by burning the coal in closed ovens or furnaces. It can then be used as a different type of fuel, which burns a lot hotter than coal.
A porous solid composed mainly of carbon and ash.
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.
a pure form of carbon which is formed by baking the impurities out of bituminous coal; it produces a very hot clean burning flame
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.
A processed form of coal. Processed coke burns more steadily and is stronger than metallurgical coke.
A high carbon material resembling fine ground up asphalt material. It is a by-product produced by fuel coking
A hard, dry carbon substance produced by heating coal to a very high temperature in the absence of air. Coke is used in the manufacture of iron and steel.
The solid product resulting from the incomplete combustion of coal, consisting principally of carbon; used chiefly as a fuel in metallurgy to reduce metallic oxides to metal.
solid substance left after gas and tar have been extracted from coal, used as fuel
means the solid black hydrocarbon left as a residual after the volatile hydrocarbons have been removed from bitumen by distillation.
A hard, dry substance containing carbon that's produced by heating bituminous coal to a very high temperature in the absence of air
A porous solid left over after the incomplete burning of coal or of crude oil.
a form of coal that was unlimited in supply and therefore easier and better to use. (p. 732)
A residue high in carbon content and low in hydrogen that is the final product of thermal decomposition in the condensation process in cracking. This product is reported as marketable coke or catalyst coke. The conversion factor is 5 barrels (42 U.S. gallons each) per short ton.
A solid carbon substance produced by heating coking coal in the absence of air. It is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace.
A porous, solid residue resulting from the incomplete combustion of coal heated in a closed chamber, or oven, with a limited supply of air. Coke is largely carbon and is a desirable fuel in certain metallurgical industries.
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.
" means the substance formed when coking coal is heated in a coking oven to a very high temperature in the absence of air."
Coke is a solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. The volatile constituents of the coal, including water, coal-gas and coal-tar, are driven off by baking in an airless oven at temperatures as high as 1,000 degrees Celsius so that the fixed carbon and residual ash are fused together. Most coke in modern times are produced in "by-product" coke ovens, such as the upper photograph, and the resultant coke is used as the main fuel in ironmaking blast furnaces.
