Miller, R N

This patent describes a process for solvent refining of coal at an elevated temperature and pressure in the presence of hydrogen and a hydrogen donor solvent to produce liquid hydrocarbons and normally solid solvent-refined coal. The improvement described here comprises extracting a coal feed with a binary mixture of an aromatic hydrocarbon of up to 9 carbon atoms and an alkanol of up to 6 carbon atoms at a temperature below about 300/sup 0/C, before solvent refining the coal.
