Abstract of the Disclosure A process is described for producing metallurgical coke f??m poor coking coals in which there is combined with the poor coking coals a small amount of an additive consisting of a bitumen residue obtained from hydrocracking of bitumen from tar sands. The residue used is that from vacuum distillation of a heavy hydrocarbon bottoms material obtained from hydrocracking of the bitumen. A high boiling organic residue from vacuum distillation to an equivalent atmospheric boiling temperature of 524°C. is preferred. The novel additive is superior in its ability to penetrate into cavities and provide excellent bonding of the components of the coal.
