| 摘 要： | 阐述了温和条件下煤的溶剂抽提机理，煤分子间作用力，溶剂种类对抽提率的影响。抽出物的洁净性能，抽余物的吸附性能，抽提产物表面的物化以及表面活性剂对煤的亲水/疏水性，ζ电位和氮气吸附性能的影响。结果表明，对于高阶煤，加入中性活性剂TericG12A8可以有效降低其ζ电位，增大其氮气吸附量和疏水性。

| Abstract: | The mechanism of solvent extraction at mild conditions,the effect of the interaction among the coal motecules and the different kinds of solvent to the extraction yields were expounded.The cleanness of the extracts and the adsorption character of extracts resides and the revision of surface properties through physical-chemistry methods were reviewed.Through adding the surfactants,the changes of the hydrophilicity/hydrophobicity,Zeta potential and the nitrogen adsorption volume of the coal were observed.The experiment results suggested that by adding non-ionic surfactant Teric G12A8,the surface properties could be improved effectively,the adsorption volume of the nitrogen and the hydrophobicity were enhanced. |
