Solvent Extraction of Coal - ScienceDirect. Ground coal is digested in a recycle solvent oil (anthracene oil) which behaves as a hydrogen donor. Extraction is effected at 375-450°C, but the actual extraction stage does not involve a catalyst or molecular hydrogen. The extent of extraction can be controlled, but is usually 80-90% of the coal substance.
