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.

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.

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.

Coke (petroleum), calcined A complex combination of carbonaceous material including extremely high molecular weight hydrocarbons obtained as a solid material from the calcining of petroleum coke at temperatures in excess of 1000°C (1800°F). The hydrocarbons present in calcined coke have a very high carbon-to-hydrogen ratio.

Tar, coal, high-temp., high-solids Coal Tar Solids Residue [The condensation product obtained by cooling, to approximately ambient temperature, the gas evolved in the high temperature (greater than 700 °C (1292 °F)) destructive distillation of coal. Composed primarily of a complex mixture of condensed ring aromatic hydrocarbons with a high solid content of coal-type materials.] The condensation product obtained by cooling, to approximately ambient temperature, the gas evolved in the high temperature (greater than 700°C (1292°F)) destructive distillation of coal. Composed primarily of a complex mixture of condensed ring aromatic hydrocarbons with a high solid content of coal- and coke-type materials. 648-062-00-3
