Abstract

PURPOSE: To obtain high-quality modified coal having reduced water adsorption high density and improved strength, by adding a petroleum type or coal type solvent in a specific ratio to grown coal, blending and heat-treating them under specific temperature conditions.
CONSTITUTION: ≤0.15pts.wt. petroleum type or coal type solvent having an initial boiling point of ≥250°C is added to 1pt.wt. brown coal, they are blended and heat- treated at 250W500°C, oxygen in the brown coal is separated and evaporated in the form of H2O, CO, and CO2 as much as possible and the surface of the brown coal is covered with the solvent. And the blend is shaped under conditions preferably pressure of 5W500kg/cm2 at 200W500°C. A residue oil under reduced pressure (asphalt), etc. is used as the petroleum type solvent, and coal tar, etc. is used as the coal type solvent.
