Coal Tar Production Essays - 1076 Words | Bartleby

Production The complete process of coal tar production is shown in Figure 1. The coal tar is produced by carbonization of coal. In this process, the coal is heated at 900-1100 ºC and the evolved vapors are condensed to form liquid, from which ammonia is removed to obtain a black viscous crude coal tar.
