Tar, coal, high-temperature, high- solids; Coal tar solids residue (The condensation product obtained by cooling, to approxi mately ambient temperature, the gas evolved in the high temperature (greater than 700 °C) destructive distillation of coal. Composed primarily of a complex mixture of condensed ring aromatic hydrocarbons with a high solid content of coal-type materials.)
Waste solids, coal-tar pitch coking; Coal tar solids residue (The combination of wastes formed by the coking of bituminous coal tar pitch. It consists predominantly of carbon.)
Extract residues (coal), brown; Coal tar extract (The residue from extraction of dried coal.)
Paraffin waxes (coal), brown-coal- high-temperature tar; Coal tar extract (A complex combination of hydro carbons obtained from lignite carbonisation tar by solvent cryst allisation (solvent deoiling), by sweating or an adducting process. It consists predominantly of straight and branched chain saturated hydrocarbons having carbon numbers predominantly greater than C12.)
Paraffin waxes (coal), brown-coal- high-temperature tar, hydrotreated; Coal tar extract (A complex combination of hydro carbons obtained from lignite carbonisation tar by solvent cryst allisation (solvent deoiling), by sweating or an adducting process treated with hydrogen in the presence of a catalyst. It consists predominantly of straight and branched chain saturated hydro carbons having carbon numbers predominantly greater than C12.)
Paraffin waxes (coal), brown-coal high-temp tar, silicic acid-treated; Coal tar extract (A complex combination of hydro carbons obtained by the treatment of lignite carbonisation tar with silicic acid for removal of trace constituents and impurities. It consists predominantly of saturated straight and branched chain hydrocarbons having carbon numbers predominantly greater than C12.)
Tar, coal, low-temperature, distil lation residues; Tar oil, inter mediate boiling (Residues from fractional distil lation of low temperature coal tar to remove oils that boil in a range up to approximately 300 °C. Composed primarily of aromatic compounds.)
Distillates (coal tar), upper, fluorene-free; Wash oil redistillate (A complex combination of hydro carbons obtained by the crystalli sation of tar oil. It consists of aromatic polycyclic hydrocarbons, primarily diphenyl, dibenzofuran and acenaphthene.)
Residues (coal tar), creosote oil distn.; Wash Oil Redistillate; [The residue from the fractional distillation of wash oil boiling in the approximate range of 270 °C to 330 °C (518 °F to 626 °F). It consists predominantly of dinuclear aromatic and hetero cyclic hydrocarbons.]
Distillates (coal), coke-oven light oil, naphthalene cut; Naphthalene oil (The complex combination of hydrocarbons obtained from prefractionation (continuous distil lation) of coke oven light oil. It consists predominantly of naph thalene, coumarone and indene and boils above 148 °C.)
