Pitch products are produced by Rain Carbon Inc. from coal tar pitch (CTP), a derivative of coal tar distillation, as well as from specialty petroleum feedstocks. CTP is mainly used as a binder for the production of carbon anodes essential for aluminum smelting.
The coal-to-coke transformation takes place as follows: The heat is transferred from the heated brick walls into the coal charge. From about 375°C to 475°C, the coal decomposes to form plastic layers near each wall. At about 475°C to 600°C, there is a marked evolution of tar, and aromatic

Binder Pitch: Coal Tar Pitch is a black or dark-brown amorphous residue produced by the distillation or heat treatment of coal tar. Zero QI Impregnation Pitch: It is derived from the processing of high temperature coal tar. Carbon Black Oil: Different fractions of oils are produced during coal tar distillation ranging between 180oC and 350oC.
Mar 11, 2013· Distillation of Coal Tar As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonization. We get coal deep in the earth crust in coal mines.

Destructive distillation of a tonne of coal can produce 700 kg of coke, 100 liters of liquor ammonia, 50 liters of coal tar and 400 m 3 of coal gas. Destructive distillation is an increasingly promising method for recycling monomers derived from waste polymers.
4. CHEMICAL AND PHYSICAL INFORMATION (American Wood Preserver's Association 1988). Coal tar creosote is defined by the latter organization as: A distillate derived from coal tar. As used in the wood preserving industry, creosote denotes a distillate of coal tar produced by the high temperature carbonization of bituminous coal.

Coal Tar Refining Company (CTR) has established in 1997 with 100,000 MT annual production capacity. 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.
Coal tar or crude coal tar is obtained by the destructive distillation of bituminous coal at very high temperatures. It is believed that over 10,000 different compounds make up coal tar, but only 400 or so have been identified. The main groups of compounds making up crude coal tar are 48% hydrocarbons, 42% carbon and 10% water.
COAL TAR OIL contains phenols, which react as weak organic acids and are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Phenols also generate heat with bases. Such heating may initiate polymerization.
hydrocarbons. Coal-tar pitch is the residue from the distillation of coal tar (Betts, 1997). The largest source of tar and pitch is the pyrolysis or carbonization of coal. Until the end of the Second World War, coal tar was the main source of benzene, toluene, xylenes, phenol, cresols and cresylic acids, pyridine and methyl-
Alibaba offers 102 coal tar distillation products. About 11% of these are machine oil purifier, 2% are evaporator. A wide variety of coal tar distillation options are available to you, such as new. There are 24 coal tar distillation suppliers, mainly located in Asia.
Distillation of tar - BARRETT CO - Free Patents Online. This vacuum distillation is advantageously a film distillation in which a thin film of the residue from the pipe coil distillation is caused to flow in indirect contact with the preheated coal tar while the pipe coil distillation residue is being subjected to a high vacuum.
Dec 26, 2018· The industrial production of coal tar pitch consists of the fractional distillation of the coal tar at a temperature around 400 deg C (Fig 1). By this method, the coal tar yields a series of liquid fractions suitable for different industrial applications and a residue which is solid at room temperature, called coal-tar pitch.
