| Abstract: | The inexpensive and convenient coal water mixture(CWM) additive is prepared by sulfonation modify with sulfate lignin.The structures of products are analyzed with FTIR spectrum,meanwhile,the adsorption on coal surface,the effects of solid-liquid interface free energy,the hydration shell and the rheological properties of CWM are discussed.The results show that the solid-liquid interface free energy and the hydration shell thickness can be reduced in CWM with the additive,consequently,the additive can be application in preparation of CWM,which can meet the requirements of industrial application. |

| Keywords: | lignin surfactant coal water mixture solid-liquid interface free energy hydration shell |
