The process of carbonization would last about 3 hours. Superheated steam is injected continuously into the top of a retort filled by coal. At first, in contact with cool coal, the steam condenses to water acting as a cleaning agent. While temperature of coal rises, the destructive distillation starts.

Coal tar, a black, sticky liquid thicker than water, is produced when coal is heated in the absence of air, a process called destructive distillation. Much coal tar is produced by the steel industry as it produces millions of tons of coke each year to fuel the furnaces used in separating iron from its ores.
