    摘要: An improved process for making metallurgical coke is provided which enables the use of coals that ordinarily do not yield coke of expected stability based on the rank of the coal. The comminuted coal is pretreated by contacting and reacting the coal with a halogenated hydrocarbon liquid, particularly perchloroethylene, and the pretreated coal is thereafter subjected to high temperature carbonization.
