Coke (fuel) Wikipedia

Coke is a grey, hard, and porous 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, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.

What Is the Chemical Equation for the Combustion of Coal

The chemical equation for the combustion of coal is C + O2 = CO2. In this equation, C represents the carbon in the coal, which reacts with air, represented by O2, to form carbon dioxide, or CO2. When coal combustion occurs in an environment low on oxygen, the equation C + CO2 = 2CO may result.

Coal Structure and properties of coal Britannica

Coal Coal Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalifiion proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and hydroaromatic

Subbituminous coal contains less carbon and more water, and is therefore a less efficient source of heat. Lignite coal, or brown coal, is a very soft coal that contains up to 70% water by weight. The total energy consumption in the United States for 1990 was 86 x 10 15 kJ. Of this total, 41% came from oil, 24% from natural gas, and 23% from coal.

Coal Wikipedia

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal seams al is mostly carbon with variable amounts of other elements chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
