Coal Tar and its Distillation Processes – IspatGuru

The normal yield of coal tar during the coal carbonizing process is around 4 %. Coal tar has a specific gravity normally in the range of 1.12 to 1.20, but exceptionally it can go upto 1.25. It depends on the temperature of carbonization. The lower specific gravity tars are generally produced when low carbonization

Pitch coke - RESORBENT

Pitch coke is the by-product of coke manufacturing (carbonisation). The production of coke yields large amounts of coke oven gases that are treated and used as the input for the manufacturing of a wide range of products. This is also how tars – mixtures of many thousands of hydrocarbons containing free carbon – are made.

Coal tar - Wikipedia

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. 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 railway tie preservative and used in the surfacing of

Coal-Tar Pitch Update - Buildings

Coal-tar pitch is produced by distillation of the crude coke-oven tar (obtained during the high-temperature treatment of coal to make coke or natural gas). Pitch materials are usually thick, black, or dark brown liquids or semi-solids with a naphthalene-like odor. Coal-tar pitch can typically be recognized by its sharp, burning odor.

01-09-1981  After a coking period of 15-20 h in the horizontal coke chamber an isotropic coke can be obtained in 80% yield. The low sulphur, ash and metal content of this coke are noteworthy assets. In addition to the pitch coke, coke oven gas rich in hydrogen and condensate is produced in this process. This condensate can be redistilled yielding secondary pitch.

Fractional Distillation In The Coal Tar Industry

The quality of coke oven tar is, like that of coal tar, very variable indeed, but is similar enough to enable the distiller to mix the tars and work them up together. Generally speaking, however, coke oven tar is less viscous, has a lower specific gravity , contains less naphtha and phenols, although often as much or even more total tar acids, and it leaves less pitch.
