| Abstract: | In this paper, three representative dispersants for CWS are selected to study the effects of dispersant dosage on CWS concentration and viscosity. The structure of dispersants for CWS is analysed with FTIR to study the effects of which on the surface properties of Yima Coal.The conclusion is that dispersants reduce the content of organic function on coal surface to improve the slurry properties of Yima coal. |
