• 低阶煤
• 水煤浆
• 水热处理
• 含氧基团
• 接触角 low rank coal
• coal water slurry
• hot water treatment
• oxygen-containing groups
• contact angle

The coal water slurry(CWS) prepared from low rank coals(LRC),such as lignite or subbituminous coals always has a higher viscosity and poor fluidity while the solid concentration is smaller than high rank coal water slurry.The reason is there are larger inherent moisture and oxygen composition in LRC...
