摘要: In order to improve the drying efficiency of lignite and restrain moisture re-adsorption dewatered coal, characteristics typical Chinese lignite, performances samples change in pore structure throughout entire processes were investigated this study. Lignite with four different particle size fractions dried a fixed-bed reactor temperature range 60–160°C. The re-adsorbing behaviors coal containing water contents at temperatures 20–40°C humidities 55–95%. changes raw measured by mercury intrusion porosimetry (MIP) relations between their performance explored. removal yields increased an increase time was close 100% above 120°C over after holding 40 15 min ...
