coal tar • n. a thick black liquid produced by the destructive distillation of bituminous coal. It contains benzene, naphthalene, phenols, aniline, and many other organic chemicals. The Oxford Pocket Dictionary of Current English. or even fuel like anthracite coal, is being burned; but difficulty develops when bituminous coal is the fuel used. One of the distinguishing char-acteristics of bituminous coal is that a large amount of gas and tar vapors are distilled off when it is heated. High volatile coals give off a greater amount of such gas than those known as low volatile.
coal tar definition: a black, thick, opaque liquid obtained by the destructive distillation of bituminous coal, used in making dyes, medicines, plastics, paints, etc. tar 1 (tär) n. 1. A dark, oily, viscous material, consisting mainly of hydrocarbons, produced by the destructive distillation of organic substances such as wood, coal, or peat. 2. See coal tar. 3. A solid residue of tobacco smoke containing byproducts of combustion. tr.v. tarred, tarring, tars To coat with or as if with tar. Idioms: tar and feather 1.
coal tar, product of the destructive distillation of bituminous coal. Coal tar can be distilled into many fractions to yield a number of useful organic products, including benzene, toluene, xylene, naphthalene, anthracene, and phenanthrene. It is understood that the distillation of coal is done by heating coal in an air (oxygen) free container (ie in a retort). The vertical retort is, apparently, a fairly large vertically oriented open topped cylinder with a narrowing body at the bottom of the cylinder to form a relatively small opening to allow discharge of coke (and some tar).

Excerpt from The Tars Distilled From Bituminous Coal in Hand-Fired Furnaces Box into the ash box and up through the grate to the fuel bed. Several sampling devices were inserted radially into the furnace as shown in Plate I.
These samplers were water cooled and were connected with rubber hose to a water supply and drain pipe. Additional Physical Format: Online version: Katz, S.H.

The experiments typically occurred at the atmospheric pressure in a laboratory furnace at temperatures ranging from to oC with a heating rate of 10oC/min and a holding time of 1 hour at the pyrolysis temperature.
Tar Distilled From the Coal.-The tar distilled from the coal consists of about 50 per cent of pitch and 50 per cent of hydrocarbon oils and liquid paraffins. A coal rich in tarry vapors is a most persist-ent smoke maker, as the tar constitutes the worst smoke-producing constituent of the coal.

The experiments with rapid heating to °C provided char yields of 58 (±2) wt.%, tar yields of 17 (±2) wt.%, yields of decomposition water of 9 (±1) wt.% and pyrolysis gas yields of 15 (±2) wt.%.
Generally people represent Bitumen as Tar Coal (not also Coal Tar), but few test and technical skills can give you a clear description in between both.
So I am listing the few important differences between Bitumen and Coal Tar Bitumen:. It is. Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. It may be applied to the affected area to treat psoriasis and seborrheic dermatitis (dandruff).
It may be used in combination with ultraviolet light therapy. Industrially it is a railway tie preservative and used in the surfacing of roads. Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system.
It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities.
Coal gas contains a mixture of calorific gases including hydrogen, carbon monoxide, methane. The heating of coal in the absence of air. This causes the coal to breakdown into a variety of useful products. These can be isolated and used in a variety of ways.
Destructive distillation of a ton of coal can produce kg of coke, liters o. Pitch, Coal Tar — The black or dark brown, solid or semi-solid, fusible and agglomerative residue remaining after partial evaporation or fractional distillation of coal tar.
Pitch, Mastic — A well-graded mixture of mineral matter and coal tar pitch suitably blended, cooked and laid hot manually or mechanically by a suitable float. Canned Pitch CP Bulk Pitch BP Description Durapax Coal Tar Roofing and Waterproofing Pitches are derived from base tars extracted from bituminous coal during the coking process.
A variety of feedstocks are then blended and distilled to achieve the proper specification, physical properties and performance characteristics. It’s been named so because of the presence of a tar-like & gluey type substance that is known as bitumen. Bituminous type coals are formed & created when a sub-bituminous type of coal is exposed to heating & very high pressure.
Based on the coals volatility, bituminous type coals are divided into the categories of low-volatile bituminous coal. Di Gianfrancesco, in Materials for Ultra-Supercritical and Advanced Ultra-Supercritical Power Plants, Subbituminous coal. Subbituminous coals are a type of coal whose properties range from those of lignite to those of bituminous coal and are used primarily as fuel for steam-electric power generation.
Subbituminous coals may be dull, dark brown to black, soft and crumbly at the. Bituminous coal. See also what's at Wikipedia, your library, or elsewhere.

Bituminous Roofing Hits the Market Back in the pre-World War II years, there were two bituminous substances (bitumens) that dominated the roofing industry. Coal tar pitch was a by-product of processing coal to make coke, which in turn was used in making carbon steel and electrodes for the aluminum industry.
Coal tar definition, a thick, black, viscid liquid formed during the distillation of coal, that upon further distillation yields compounds, as benzene, anthracene, and phenol, from which are derived a large number of dyes, drugs, and other synthetic compounds, and that yields a final residuum (coal-tar pitch), which is used chiefly in making pavements.Bitumens should not be confused with coal-derived products such as coal tars or coal-tar pitches, which are distinctly different substances.
While bitumens are derived from petroleum, coal-tar products are derived from the high-temperature carbonization of bituminous coals (> °C) and are by-products of gas and coke production.Crude Coal Tar is a by product of the Coking process.
Coking is the process of heating coal in coke ovens to drive volatile matter from it. Metallurgical Coke is used as a fuel and reducing agent in the production of iron, steel, ferro-alloys, elemental phosphorus, calcium carbide and.
