Zusammenfassung:	A binder for making metallurgical coke and a process for making the binder. The binder is thermally hydrocracked pitch which has been de-ashed. The binder may be mixed with low rank bituminous coal, heated to make coke which is acceptable as a metallurgical coke. The thermally hydrocracked pitch may be de-ashed by mixing with a solvent, and separating the insoluble portions from the soluble portions using a centrifuge. The soluble portions may be separated from the solvent, for example, in a fractionating section, and used as the binder with poor coking coal to make metallurgical coke.
