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.

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 (coal), naphtha cracking ethylene manuf. by-product Coke formed by cooling, to approximately 1500°C, hot acetylene containing split gases from aromatic residual oil produced from ethylene production by naphtha cracking at 800°C to 900°C (427°F to 482°F) (coal derived).

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
