The coal tar pitch that we are supplying to our clients is widely used for manufacturing of basic refractories. The addition of coal pitch to castable refractory that is used for main troughs of blast furnaces is aimed to improve prevention of infiltration of slag and molten iron
Distillates are made up of crude coke oven tar components, which are produced during the high temperature coking of bituminous coal. Carbon pitch boils between 100°C and 400°C during the distillation process. Refined chemical oil distills between 210°C and 315°C.
steel production the electrode demand is today growing. Green graphite electrodes contain about 20 % of coal tar pitch so that about t of coal tar per ton of graphite electrode is indirectly directed towards this application. The steel industry plays then a dual role concerning the carbon materials.

The process of manufacturing coaltar pitch from a coaltar obtained by distillation of coal in a fluidized bed; comprising the steps of forming a mixture at a temperature of 100 C. of equal weights of anthracene oil and said coaltar, and distilling said mixture under a pressure of 18 mm. of mercury until the residue reaches a K. S. softening ...
Coal tar pitch is a black or darkbrown amorphous residue produced by the distillation or heat treatment of coal tar. It is a solid at room temperature and exhibits a broad softening range instead of a defined melting temperature.
The resulted powder is conditioned according to the particles size distribution (screening). The last step of powder preparation process is blending the powder with a binder. Coal tar pitch, petroleum pitch or synthetic resins are used as binders. The powder preparation process is presented in the scheme below.
Sealcoat used in the central, southern, and eastern commonly contains coaltar pitch, a byproduct of the manufacturing process, which is made up of at least 50% PAHs. Pavement sealants that contain coaltar, therefore, have extremely high levels of PAHs compared to other PAH sources such as vehicle emissions, used motor oil, and tire ...

Graphite electrodes can be used in electric arc furnace steel production since they perform well in the severe heat and temperatures generated in this environment. Graphite electrodes also are used to refine steel in ladle furnaces and in other smelting processes. Graphite electrodes are made from calcined needle coke and coal tar pitch (CTP).

Coal tar pitch is a byproduct of converting coal into coke for steel manufacturing—and, way back when, of gasifying coal to make illuminating gas—whereas asphalt is a byproduct of refining petroleum. Visually they're similar, but chemically they are much different. In general, the builtup roofing (BUR) industry has been declining since ...

As for coal tar preparation technology, coal carbonization processing and coal hydropyrolysis are mature and has been applied to industry production. In comparison, hydrogenation of coal tar is just at the development. In term of coal tar processing technology, the present leading directions are how to manufacture clean fuel as well as phenol.
Sealcoating applies one or more layers of a coal tar pitch or asphalt cement mix to form a protective barrier against oil, gasoline, diesel fuel, road salt, and water. Concrete. Concrete. Concrete paving companies are road construction and paving services that can...
Production The complete process of coal tar production is shown in Figure 1. The coal tar is produced by carbonization of coal. In this process, the coal is heated at ºC and the evolved vapors are condensed to form liquid, from which ammonia is removed to obtain a black viscous crude coal tar.
