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).

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.

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.

Naphtha (petroleum), light thermal cracked Low boiling point thermally cracked naphtha [A complex combination of hydrocarbons from distillation of products from a thermal cracking process. It consists predominantly of unsaturated hydrocarbons having carbon numbers predominantly in the range of C 4 through C 8 and boiling in the range of approximately -10 °C to 130 °C (14 °F to 266 °F).] A complex combination of hydrocarbons from distillation of products from a thermal cracking process. It consists predominantly of unsaturated hydrocarbons having carbon numbers predominantly in the range of C4 through C8 and boiling in the range of approximately minus 10°C to 130°C (14°F to 266°F). 649-316-00-6

Naphtha (petroleum), heavy catalytic cracked Low boiling point cat-cracked naphtha [A complex combination of hydrocarbons produced by a distillation of products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly in the range of C 6 through C 12 and boiling in the range of approximately 65°C to 230°C (148°F to 446°F). It contains a relatively large proportion of unsaturated hydrocarbons.] A complex combination of hydrocarbons produced by a distillation of products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly in the range of C6 through C12 and boiling in the range of approximately 65°C to 230°C (148°F to 446°F). It contains a relatively large proportion of unsaturated hydrocarbons. 649-289-00-0
