Abstract
A slurry of coal particles is dewatered by agglomerating the coal particles using a hydrocarbon binder at an elevated temperature to obtain coal pellets which are then heat treated. Gases released by the pellets during heat treatment may be heat exchanged with the slurry or burned to produce heat for the heat treatment, steam for the heat treatment, or to provide mechanical energy for the agglomeration.
