ABSTRACT:
A process is described for producing metallurgical coke from 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.degree. 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.
