Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal.It is a type of creosote. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railroad tie preservative and used in the surfacing of roads. Coal tar was listed as a known human carcinogen in the first Report on Carcinogens from the U.S. Federal Government.
1. As a fuel, due to its large solid composition, it is generally mixed with heavy oil or made into slurry for use,
which can partially replace heavy oil.
2. For the production of carbon electrodes, the degree of carbon graphitization in coal tar pitch is relatively
high, and it can be used as electrode material, as well as as a sizing agent and binder.
3. The coating is mainly used for waterproof coating of buildings and pipes after treatment and processing.
Epoxy coal tar pitch coating is one of the most widely used coatings.
4. Road building and building materials are generally mixed with petroleum asphalt. Compared with coal tar
asphalt and petroleum asphalt, there is an obvious quality gap and durability gap.
5. Needle coke, activated carbon, carbon fiber and other high value-added products. Coal tar pitch has high
carbon residue value, many graphitization components and easy processing.
6. Other uses such as linoleum
