【摘要】：采用反气相色谱法(IGC)研究原煤在温度433.15、443.15、453.15、463.15和473.15 K时的三维溶解度参数(HSP),并使用外推法得到原煤室温(298.15 K)时HSP的色散力分量(δd)、极性力分量(δp)、氢键力分量(δh)以及校正溶解度参数(δt)分别为δd=20.83(J·cm~(-3))~(1/2),δp=11.95(J·cm~(-3))~(1/2),δh=11.08(J·cm~(-3))~(1/2),δt=26.44(J·cm~(-3))~(1/2)。同时,采用汉森三维溶解度参数软件(HSPi P)模拟原煤在室温下的HSP,得到δd=19.92(J·cm~(-3))~(1/2),δp=11.18(J·cm~(-3))~(1/2),δh=11.47(J·cm~(-3))~(1/2),δt=25.56(J·cm~(-3))~(1/2)。IGC与HSPi P得出的数据一致,研究结果为煤的热力学性质研究及其溶胀剂的选择等应用提供了参考。
[Abstract]:The three-dimensional solubility parameters of raw coal at 433.15443.153.15453.15463.15 and 473.15 K were studied by inverse gas chromatography (IGC). The dispersion force components of HSP at room temperature of 298.15K were obtained by extrapolation method. The components of polarity force (未 p, hydrogen bond force) and corrected solubilization were obtained by extrapolation method. The resolution parameters (未 _ t) are 未 _ d ~ (20.83) J / cm ~ (-1 / 2), 未 _ p ~ (11.95) J ~ (-1 / 2), 未 _ h ~ (11.08) J ~ (-1 / 2), 未 _ t _ (26.44) J ~ (-1 / 3) ~ (-1 / 2) ~ 1 / 2 ~ (-1) ~ 1 / 2 ~ (-1 / 2) ~ (-1 / 2) respectively, and 未 t _ (26.44J) ~ (-3) ~ (1 / 2) ~ (-1 / 2) ~ (-1 / 2) ~ (-1 / 2) ~ (-1 / 2). At the same time, using Hansen three-dimensional solubility parameter software (HSPi P) to simulate the raw coal HSPs at room temperature, we have obtained 未 dl 19.92J cm-1 / 2, 未 p 11. 18 J / 1 / 2, 未 h 11. 47J cm-1-3H 1 / 2, 未 H 11. 47J cm-1-3H / 2, 未 tr 25. 56J cm~(-3))~(1/2).IGC and HSPi P. The results provide a reference for the study of the thermodynamic properties of coal and the selection of swelling agents, etc. The results of the study provide a reference for the study of the thermodynamic properties of coal and the selection of the swelling agent, etc. The results of the study provide a reference for the study of the thermodynamic properties of the coal and the selection of the swelling agent.
