Coke (coal) The cellular carbonaceous mass resulting from the high temperature (greater than 700°C (1292°F)) destructive distillation of coal. Composed primarily of carbon. May contain varying amounts of sulfur and ash.

Coke (coal), secondary pitch A carbon-containing residue from the coking of air blown pitch coke oil and/or pitch distillate. Composed primarily of isotropic carbon , it contains small amounts of sulfur and ash constituents.

Coke (petroleum) A solid material resulting from high temperature treatment of petroleum fractions. It consists of carbonaceous material and contains some hydrocarbons having a high carbon-to-hydrogen ratio.

Tar, coal, high-temp., residues Coal Tar Solids Residue [Solids formed during the coking of bituminous coal to produce crude bituminous coal high temperature tar. Composed primarily of coke and coal particles, highly aromatized compounds and mineral substances.] Solids formed during the coking of bituminous coal to produce crude bituminous coal high temperature tar. Composed primarily of coke and coal particles, highly aromatized compounds and mineral substances. 648-061-00-8

Fuel gases, coke-oven The gas evolved from the high temperature (greater than 700°C (1292°F)) destructive distillation of coal after the removal of high temperature coal tar, coke oven light oil, and ammonia liquor. Composed primarily of hydrogen and methane. May contain ammonia, hydrogen sulfide, and low molecular weight hydrocarbons.

Tar, coal, high-temp., distn. and storage residues Coal Tar Solids Residue [Coke- and ash-containing solid residues that separate on distillation and thermal treatment of bituminous coal high temperature tar in distillation installations and storage vessels. Consists predominantly of carbon and contains a small quantity of hetero compounds as well as ash components.] Coke- and ash-containing solid residues that separate on distillation and thermal treatment of bituminous coal high temperature tar in distillation installations and storage vessels. Consists predominantly of carbon and contains a small quantity of hetero compounds as well as ash components. 648-059-00-7
