WEBCoal 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 .
WEBTo supply themselves with coke, steelmakers developed the process of destructive distillation of coal. The early sources of phenol were the destructive distillation of coal and the manufacture of methyl alcohol from wood. In both cases, phenol was a byproduct. Recovered volumes were limited by whatever was made accidentally in the process.
WEBThis process is still used in Scandinavia for tarmaking. Coal tar pitch volatiles (CTPV) are the result of destructive distillation of bituminous coal. These CTPVs often contain polynuclear aromatic hydrocarbons (PNA's), which sublime readily and are carcinogenic. Other examples of substances that are commonly destructively distilled to ...
WEBSolution. The nature of the products of the destructive distillation of bituminous coal, in absence of air, depends largely upon the temperature at which the process is carried out. When such coal is heated to 450°500° C. it yields gas and oily vapours consisting chiefly of paraffin hydrocarbons.
WEBNov 12, 2023 · Coal Tar Production. Destructive distillation of coal is one of the oldest and most wellestablished appliions of this process.
