crude coal tar for deeply processing
1. Description
Coal tar is a kind of organic compound (mainly aromatic hydrocarbon), and it is an important by-product in the coal processing industry. Its specific gravity is greater than that of water. It has certain dissolubility and special odor. And it is flammable and corrosive. Coal tar is the basic raw material of chemical products like synthetic plastic, synthetic fiber, pesticide, dyestuff and medicine as well as basic raw material in such sectors as metallurgy, construction, textile, paper making and traffic.
2. Properties
Coal tar is a kind of black or black brown sticky liquid got during the process of coal coking .Coal tar has special distinctive odor. Its relative density is 1.18~1.23 and the open flash point is at 200°C, and it is slightly dissolvable in water and soluble in organic solvent like benzene, alcohol, ethyl ether, chloroform, acetone etc.. Its fume and air can become explosion mixture, meanwhile, if it meets open fire, the heat, its container may have the danger to craze and explode. Therefore, we should be careful when we carry them.
3 Technical data
| index name | NO. 1 | NO. 2 |
| density g/cm3 | 1.15-1.21 | 1.13-1.22 |
| naphthalene content, % ≥ | 7.0 | 7.0 |
| moisture, % ≤ | 4.0 | 4.0 |
| ash, % ≤ | 0.13 | 0.13 |
| viscosity, ≤ | 4.0 | 4.2 |
| toluene insolubles content, % | 3.5-7.0 | ≤ 9 |
4 Application
By fractionation, it can get dutrex, alkane, phenols and also can produce asphalt felt, fuel and carbon black from coal tar. Coal Tar can be used in electricity generation, coking coal for steel manufacturing and industrial process heating and medicated shampoo, soap and as a treatment for dandruff.
5 Advantages
By using advanced coal tar deep processing technique and equipment, we can extract medium-temperature pitch, modified pitch, industrial naphthalin (solid and liquid), fuel oil, light oil, hydroxybenzene oil, carbazole, indole and other products, falling into over 30 kinds. The above series products are basic raw materials of chemical products like synthetic plastic, synthetic fiber, pesticide, dyestuff and medicine as well as basic raw materials in such sectors as metallurgy, construction, textile, paper making and traffic.
