Most coal tar is obtained as a byproduct in pyrolysis of coal to coke for steel making. At the beginning of the 1980s world output of coal tar was about 18m. tonnes, of which 14m. tonnes came from coke production. Production of coal tar has fallen considerably in recent decades.
Coal, oil shale, and tar sand are carbonaceous materials that can serve as future energy and chemical sources when oil and gas are consumed. The H/C ratio of these materials is lower than in most crude oils. As solids or semisolids, they are not easy to handle or to use as fuels, compared to crude oils.
coal tar distillation (eiri1092) Coaltar is produced by the dry distillation of coal and is therefore a by product in the manufacture of coal gas. For a considerable time after the discovery of coal gas, the tar produced was considered merely an encumbrance and was used mainly as a pigment or fuel.

Coal tar is a black, viscous, thick liquid from which a great number of chemical compounds are derived. The first fraction is obtained in the distillation of coal tar contains many aromatics, among them benzene, toluene and xylem. Benzene is the lightest fraction obtained from the distillation of coal tar hydrocarbons.
Coal Tar Dyes Coal Tar Dyes What is it? Coal tar dyes are artificial coloring agents made by combining various aromatic hydrocarbons like toluene, xylene, benzene, which are obtained from the distillation of bituminous coal. Coal tars are also made from petroleum distillates. Coal tar is a brown or black liquid of extremely high viscosity.

Sep 02, 2013· In fact, coal oil and kerosene oil are distinctly different substances, although they can both be used in similar ways as a fuel source. In simple terms, the main difference between coal oil and kerosene oil is in their origins; coal oil is extracted from a type of soft, oily coal called cannel coal (or sometimes candle coal).

For 1 mt of iron about mt of coke is used so that from the mt of coal needed 2200 t of coal tar are produced by the cokery. In India the apparent capita consumption of finished steel is about 60 kg while it reaches 450kg in China where 700 mtpy of crude steel are produced today.
In this report, "asphalt" is considered to be the residue, essentially uncracked, from the fractional distillation of crude petroleum. Coal tar pitch is defined as the residual product from the distillation of crude coal tar, a cracked material, which is formed during the coking of coal.

Bitumen is also frequently called tar or pitch—though, properly speaking, tar is a byproduct of the carbonization of coal and pitch is actually obtained from the distillation of coal tar. Bitumen is defined by the Geological Survey as an extraheavy oil with an API gravity less than 10° and a viscosity greater than 10,000 centipoise.
