Tar is a sticky black liquid made of thick is a natural substance, oozing out of the ground in places like the La Brea tar it is made by heating coal inside a chemical apparatus.. Most tar is produced from coal as a byproduct of coke production, but it can also be produced from petroleum, peat or "destructive distillation" of a ton of coal can produce 700 kg of ...

Coal tar is essentially the thick viscous liquid which is obtained by the carbonisation of coal, and is a byproduct in the ordinary manufacture of coal gas. It should be differentiated from all the other forms of tar. When coal is submitted to dry distillation in horizontal or vertical retorts, the products of carbonisation are gas, ammoniacal ...

Residues from naphthalene collection and recovery operations from the recovery of coke byproducts produced from coal. (T) K147: Tar storage tank residues from coal tar refining. (T) K148: Residues from coal tar distillation, including but not limited to, still bottoms. (T)
Creosote is a category of carbonaceous chemicals formed by the distillation of various tars and pyrolysis of plantderived material, such as wood or fossil fuel. They are typically used as preservatives or antiseptics. Some creosote types were used historically as a treatment for components of seagoing and outdoor wood structures to prevent rot (, bridgework and railroad ties, see image).

A number of carbonization processes exist. The carbonization conversion typically occurs through pyrolysis or destructive distillation. It produces condensable coal tar, oil and water vapor, noncondensable synthetic gas, and a solid residue char. One typical example of carbonization is .
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
Coal tar causes increased sensitivity to sunlight, so skin treated with topical coal tar preparations should be protected from sunlight. The residue from the distillation of hightemperature coal tar, primarily a complex mixture of three or more membered condensed ring aromatic hydrocarbons, was listed on 28 October 2008 as a substance of very ...
A black, viscous tar made by the destructive distillation of coal (to make coke and town gas); it contains a great number of compounds including hydrocarbons and phenols; used in the preparation of medicated soap and shampoo, and industrially for the manufacture of very many products. 1989, Alain Chauvel, Gilles Lefebvre, Petrochemical Processes: Major ...

Coke is a fuel with a high carbon content and few impurities, made by heating coal in the absence of air. It is the solid carbonaceous material derived from destructive distillation of lowash and lowsulfur bituminous made from coal are grey, hard, and coke can be formed naturally, the commonly used form is synthetic.

The company''s operations focus in refining and distillation of Coal Tar in order to producing valuable chemical derivatives. CTR is the greatest Coal Tar Refining Company in Middle East and the most modern technology is applied by our refinery.
Lowboiling liquid separated from coal tar by distillation. Contains benzene, toluene, xylenes, cumenes, coumarone and indene, among other substances. Colorless to yellow with a pleasant odor. Floats on water. Irritating vapor. Flash point is typically below 80° F
Coal tar is essentially the thick viscous liquid which is obtained by the carbonisation of coal, and is a byproduct in the ordinary manufacture of coal gas It should be differentiated from all the other forms of tar When coal is submitted to dry distillation in horizontal or vertical retorts, the products of carbonisation are gas, ammoniacal.
Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive can be produced from coal, wood, petroleum, or peat.. Mineral products resembling tar can be produced from fossil hydrocarbons, such as petroleum. Coal tar is produced from coal as a byproduct of coke production.
Coaltar pitch is a thick black liquid that remains after the distillation of coal tar. It is used as a base for coatings and paint, in roofing and paving, and as a binder in asphalt products. Both coal tar and coaltar pitch contain many chemical compounds, including carcinogens such as benzene.
The primary objective of coal tar distillation process is to produce a number of tar acid products from the crude tar. The number of fractions, and size of fractions etc., which are to be taken off when tar is distilled is dependent on so many factors. The quality of tar plays a big part. Also, the kind of plant available for distillation is an ...
tar obtained by destructive distillation of coal, it is less viscous as it is boiled with volatile fluids like kerosene bitumen obtained by fractional distillation of crude oil, has more ...
Dry Distillation.—In this process the substance operated upon is invariably a solid, the vapours being condensed and collected as in the other methods. When the substance operated upon is of uncertain composition, as, for example, coal, wood, coaltar, c., the term destructive distillation is employed.
Creosote is a tarbased preservative that is commonly used for utility poles and railroad ties (UK: railway sleepers). Creosote is one of the oldest wood preservatives, and was originally derived from a wood distillate, but now, virtually all creosote is manufactured from the distillation of coal tar.
Coal tar definition is tar obtained by distillation of bituminous coal and used especially as an industrial fuel, in making dyes, and in the topical treatment of skin disorders.
