TREATMENT OF COAL FOR THE PRODUCTION OF CLEAN SOLID FUEL AND/OR LIQUID TURBINE FUEL Abstract A two stage coal solubilization process is described comprising a relatively mild first stage operation followed by a second stage operation, the severity of which is controlled as a function of the final product desired - thereby providing at least a three product mode operation. The first stage comprises the thermal solubilization of coal in a hydrogen donor material containing 10 - 50% by weight phenols at a temperature less than 800°F and a residence time restricting the formation of aromatics and the loss of hydrogen. Insufficiently dissolved material and ash is thereafter separated, such as by filtration before processing in a second stage, generally more severe operation. The severity of the second stage operation and conditions employed are selected to produce one of desulfurized coke, a solid product which upon heating is a flowable fluid or a hydrogenated product boiling in the boiling range of turbine fuel.
