  • [PDF] Study on the Preparation of Coal Water Slurry

    Coal water slurry (CWS) is a new type of fuel with good rheology and stability. In this paper, the effects of two dispersants on the viscosity and water separation rate of coal water slurry were studied. The results show that when the CWS concentration is 67%, the viscosity of coal slurry added with sodium dodecyl sulfate is 986 mpas, and the viscosity of coal slurry added with sodium ...

    2013-1-1  Phase Inversion-based Coal-CO2 Slurry preparation: the PHICCOS process The proposed PHICCOS process for the preparation of coal-CO2 slurry at ambient temperature is presented in Figure 2. The CO2 slurry is prepared via coal-water slurry (CWS); the phase inversion behavior, observed in the LICADO experiments, allows the separation of coal from the aqueous phase in the presence of CO2.
