摘　　要：提出了氢气/MeOH的多参数亥姆霍兹能显式状态方程,并由实验数据得到了基于亥姆霍兹自由能状态方程的4个特性参数。结果表明,新的状态方程能够很好地预测VLE和饱和液体密度。液体摩尔分数和蒸汽摩尔分数的平均偏差(ARD)分别为9.37和3.66,最大密度偏差为1.48%。A multi-parameter Helmholtz energy explicit equation of state for hydrogen/MeOH was proposed,and four reducing parameters was obtained based on experimental data collected.It was shown that the new equation of state predicted the VLE and statured liquid density very well.The average reduced deviations(ARD)of liquid mole fraction and vapor mole fraction were 9.37 and 3.66,respectively.The maximum density deviation is 1.48%.
