The impregnating-grade coal tar pitch is a special type of coal tar pitch, which has a low content (0-3 %) of quinoline insolubles (QI), besides having lower values of softening point (SP), toluene insolubles (TI), coking yield and specific gravity (SG), compared to those of the binder-grade coal tar pitch.
Coal-tar pitch is a thick black liquid that remains after the distillation of coal tar. It is used as a base for coatings and paint, in roofing and paving, and as a binder in asphalt products. Both coal tar and coal-tar pitch contain many chemical compounds, including carcinogens such as benzene.
Flow Measurement of Hot Pitch during Coal Tar Distillation. In one of the world's largest coal tar refineries, the delivered raw material is distilled to obtain technical oils and aromatics, which serve as valuable basic materials for the dye and pharmaceutical industries.
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

The binding process should have similarities with what occurs in Soderberg paste for submerged arc furnace electrodes, common in the ferroalloy industry, or with artificial graphite electrodes for electric arc furnaces and ladle furnaces used in the steel industry, as these processes are also based on petroleum coke and coal tar pitch.
The production of tar pitches and binding agents for the manufacture of high-quality carbon materials is considered. The progressive scarcity of coal-tar pitch is noted.
In this paper, a three-dimensional numerical model has been developed to study the process of oxidative weight increment of coal tar pitch in a rotating kiln. Based on the two-fluid method, the gas phase is modeled by realizable k - ε turbulent model and the solid phase is modeled by kinetic theory of granular flow. The dense gas-solid flow, heat transfer, and oxidation reaction for the bed ...
Liu et al. utilized the coal tar pitch with a high softening point of 280 °C to prepare isotropic hard carbon spheres by the emulsion system. Similarly, the preparation process of high softening point pitch is complicated, and the as-prepared pitch spheres also need post-oxidation for infusibility.
Flow diagram of coal to coal-tar-pitch process . Coal tar is a byproduct of the coking, liquefaction, or gasification of coal. Coal-tar pitch is the residue that remains after the distillation of coal tar. Coal tar and coal-tar pitch are used in coal-tar-based sealcoat products, although use of coal-tar pitch is more common than use of coal tar.
Dec 26, 2018· The process of distillation gives a variety of valuable chemical products. The residue of distillation is coal tar pitch, which is further processed into coal tar pitch of desired chemical and physical properties. The primary objective of coal tar distillation process is to produce a number of tar acid products from the crude tar.
Apr 30, 2020· Tar and pitch, usually used for paving or burned as waste, could be studied for more uses. The researchers believe a post-fossil fuels future requires new uses for these products.
