Solvent extraction phenol from coal tar were carried out with novel composite YH-3 as extraction agent, and the high flux centrifugal extractor was used as extraction device. Under the premise of high phenol extraction rate, composite YH-3 extraction agent reduces π–π interaction between phenolic compounds and aromatic hydrocarbons, thus decreasing the entrainment of neutral oil.
Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. It may be applied to the affected area to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railway tie preservative and used in the surfacing of roads.

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 tar creosotes consist of aromatic hydrocarbons, anthracene, naphthalene, and phenanthrene derivatives. At least 75% of the coal tar creosote mixture is polycyclic aromatic hydrocarbons (PAHs). Unlike the coal tars and coal tar creosotes, coal tar pitch is a residue produced during the distillation of coal tar. The pitch is a shiny ...

Processing Coal Tar Before the synthetic age of manufacturing, pyridine was obtained from coal tar. Industrial Process Processing coal tar [Diagram 2] commences by cooking coal at > 800°C. The non-condensed gases undergo "scrubbing" (Considine,a. 1974) which is the term used when it passes a NH4 separator containing H2SO4.
Depending upon the thermal conditions, coal tar typically contains 20–35% (w/w) non-distillable coal-tar pitch—the remainder of the distillable tar. Being flammable, coal tar is sometimes used for heating or to fire boilers and, like most heavy fuels, requires heat before it will flow easily. Coal tar was a component of the first sealed ...
The invention discloses a low-temperature dry distillation method of coal, relates to the technical field of full and reasonable utilization of coal resources and particularly relates to a dry distillation method of coal. The method disclosed by the invention can be used for solving the technical problem that the energy consumption is high and the treatment difficulty is great as existing coal ...
Coal tar distillates are derived from the distillation of coal tars at coal tar refinery facilities. They are made of complex combinations of compounds, mainly aromatic hydrocarbons. Their composition varies based on their source, the heating temperature, and the distillation temperature for the distillates.

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.
The destructive distillation of wood is also known to produce several other compounds of commercial value, such as terpenes and tar. One of the most prominent applications of destructive distillation is in the processing of coal in order to obtain several commercially important compounds such as coke, ammonium hydroxide, coal gas, and coal tar.
