Coal is a black or brown, solid, combustible mineral formed by the alteration of prehistoric plant life by bacterial decomposition, with subsequent chemical changes caused by temperature and pressure. These processes result in a range of carbonaceous materials, the first of which is peat and the last of which is graphite (pure carbon). The coals lie between these two extremes  

The destructive distillation (heating in the absence of oxygen) of coal (mostly bituminous coal) at temperatures ranging from 500 to 1200°C, generates a number of derivatives  

Coal tar contains an estimated 10,000 compounds, many of which are important organic chemicals. The use of coal tar as a source of these compounds has been largely relegated to a position below numerous synthetic processes, primarily based on petroleum. Fractionation of coal tar yields the following (approximate temperatures and yields given)  

5% Light oil syn. coal tar distillates, coal tar solvents, or coal tar oil. a highly flammable mixture of toluene, xylene, cumenes, etc.

Pitch, a dark brown or black residue of toxic aromatic hydrocarbons and other compounds often used as road and roofing tar. Prilled coal tar is coal tar pitch manufactured into small globules or granules.

A schematic diagram of a prill tower is given in Fig. 7.7. Some details of an installation for fertilizer materials are listed in Table 1.2. Melt is provided to the prilling devices at the top of the tower from reactor/evaporator systems in the case of a fertilizer material such as ammonium nitrate or from a melt tank in the case of fusible materials such as petroleum wax and coal tar pitch. Melt droplets travel counter-current to cooling air and the solid prills are conveyed away from the bottom of the tower to appropriate downstream treatments such as cooling, clay treatment and storage.
