Semicoke

a solid fuel residue obtained by the low-temperature carbonization of solid fuels. The properties and composition of semicoke are determined by the type of fuel and the method of low-temperature carbonization used. Semicoke contains up to 10–15 percent volatile matter, as well as undesirable impurities of ash and sulfur. It is an easily ignited, smokeless fuel with a high heat of combustion—not less than 309 megajoules/m³(7,400 kilocalories/m³). Varieties with a low ash content may be produced in the form of large cakes and are used as an efficient fuel, especially for domestic heating. Fine semicoke serves as an energy-producing fuel and is added to coking charges.
