Coal Tar. Richard D. Phillips, in Encyclopedia of Toxicology (Second Edition), 2005 Uses. Coal tar is a viscous liquid mixture of hydrocarbon compounds, derived along with coke, from the destructive distillation of coal in coking ovens. Coal tar itself may be subjected to distillation, a process that separates groups of the components of coal tar from groups of others.

Destructive distillation is a chemical process. During destructive distallation decomposition of unprocessed material is caused by heating the material to a high temperature. The term usually applies to processing of organic material in an area with little or no oxygen or other reagents, catalysts, or solvents. These would include things such ...

Destructive distillation is the process of decomposing a material by heating in a closed container in an inert atmosphere and collecting off the volatile constituents. Destructive distillation of coal produces many byproducts. In the process, heated coal turns into coke, ammonia dissolves in water to form ammonia liquor and coal gas and coal ...

gasifier. (Show more) coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a byproduct.

Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization . Carbonization differs from coalification in that it occurs much faster, due to its reaction rate being faster by many orders of magnitude.
