液态甲烷的高温密度物态方程理论研究
DOI: 10.11858/gywlxb.1998.02.008, PP. 120-124
Keywords: 液态甲烷,作用势,物态方程,分解反应
Abstract:
采用热力学统计理论研究了液态甲烷在高温高压下分子分解反应特点及该体系的物态方程。着重讨论了体系中CH4-H2分子间有效势对体系化学反应平衡及物态方程的影响，并根据实验Hugoniot点(pH,V)优化确定出其exp-6势函数中的参数值。该势函数的排斥部分值比理想混合条件下Lorentz-Berthelot规则给出的势函数值低约50%，预示着高压下CH4和H2之间存在着某种亲合性。用该势函数计算得到的p-T线与现有的两个实验点符合很好。还讨论了CH4-H2之间的有效作用势参数对CH4分子冲击离解度（x）的影响。
