Coal tar | stone compound | Britannica
Coal tar, principal liquid product resulting from the carbonization of coal, i.e., the heating of coal in the absence of air, at temperatures ranging from about 900 to 1,200 °C (1,650 to 2,200 °F).Many commercially important compounds are derived from coal tar.. Low-temperature tars result when coal, peat, lignite, or stone are carbonized at temperatures not exceeding 700 °C (1,300 °F).

Tar - Wikipedia
Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation.Tar 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.
Coal Tar - an overview | ScienceDirect Topics
Coal-tar creosote, also referred to as creosote by the EPA, is formed by fractional distillation of crude coal tars.This compound is used as a stone preservative that acts as a fungicide and pesticide applied in a pressure treatment process, which involves pressurized treating cylinders that force pesticide penetration into the wood.
Coal gasification - Wikipedia
Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before ...
