Get PriceThe water-swollen coal in CWS gives much higher hydrophilicity in comparison with coal before the preparation of CWS Accordingly when methanol ethanol and 2-propanol with hydrophilic nature are added into the as-prepared CWS the coal content in CWS is diluted due to hydrophilic alcohols homogeneously mixed with water-swollen coal particles which results in a falloff in slurry viscosity
