摘要

摘要: 采用流体力学参数法研究了煤沥青可溶组分TS在甲苯中的缔合行为，确定了TS在甲苯中不同温度下的临界缔合浓度，并计算出缔合过程中成核阶段和成团阶段的缔合动力学参数。结果表明，293~353 K，TS溶液黏度随浓度的增加而增加，在13~26 g/L的浓度时出现了拐点，且拐点随温度升高而沿坐标轴方向右移。成核阶段和成团阶段均为一级缔合反应，两阶段活化能分别为17.25和12.41 kJ/mol。

Abstract: The association behavior of coal tar pitch soluble components TS in toluene was studied by hydromechanics method. The critical association concentrations of TS in toluene were obtained by viscosity curves at different temperatures. The kinetics parameters of nucleation and micelle stage in association process were calculated. The results show that the viscosities of TS solution increase with increasing concentrations at 293~353 K, and the turning-points appear between 13 and 26 g/L. The turning-points shifted backward along the axis with increasing temperatures. Both the nucleation and micelle stage are first-order associated reaction. The activation energies for the two stages are 17.25 and 12.41 kJ/mol, respectively.
