新疆伊犁南台子煤热力学参数的实验测定
|
摘要
采用气相色谱法,测定了新疆伊犁南台子煤的表面性质。以正己烷、正庚烷、正辛烷、正壬烷作为非极性探针测定其表面色散自由能。经计算得出煤在323K、333K、343K、353K下的表面色散自由能(γds),分别为41.90mJ/m~2、40.97mJ/m~2、38.65mJ/m~2和36.44mJ/m~2。结果表明,煤表面色散自由能随温度升高呈线性降低。此外还计算了煤的无限稀释活度系数、溶剂和煤的相互作用参数,以及煤的溶解度参数。结果显示,这些参数都随温度的升高而降低,表明温度的升高有利于煤的溶解。此结果为煤表面性质提供了数据。
The surface properties of Nantaizi coal in Yili,Xinjiang were determined by gas chromatography.The surface dispersion free energies of n-hexane,n-heptane,n-octane and n-nonane were measured with nonpolar probe. The surface dispersion free energy( γds) of coal at 323 K、333 K、343 K、353 K is 41.90 mJ/m~2、40.97 mJ/m~2、38.65 mJ/m~2 and 36.44 mJ/m~2. The results show that the dispersion free energy of coal surface decreases linearly with the increase of temperature. In addition,the infinite dilution activity coefficient of coal,the interaction parameter between solvent and coal and the solubility parameter of coal are calculated. The results show that these parameters decrease with the increase of temperature,which indicates that the increasing of temperature is beneficial to the dissolution of coal. The results provide data for coal surface properties.
