ABSTRACT:
A method of producing dry, pulverulent, low-density, high-porosity, high-permeability, highly-reactive carbonaceous fuel from slurries of coal and alcohol or stabilized suspensoids of coal and alcohol by single stage flashing. The slurries or suspensoids are heated under pressure to a temperature sufficient to effect single stage flashing of substantially all of the alcohol. The product resulting from flashing then is separated into vapors and solid particulate carbonaceous material. The vapors are condensed into alcohol for reuse and the particulate carbonaceous material is processed further or used as desired.
