Process for dewatering peat |
(57) A process for the removal of water from a wet material comprising combustible organic
solids to form a solid autothermally combustible fuel comprises the steps of contacting
the material with a dewatering liquid comprising a water-immiscible solvent and dissolved

wherein the wet material is preferably pre-treated with an absorbent material comprising
a water swellable polymer to effect preliminary drying of the wet material.
