本文应用自由焓极小值原理详细推导了含有惰性组分的复杂气态物系化学平衡的计算方法。得到改进的W-J-D法及拉格朗日乘子法。并对天然气蒸汽转化制合成气过程的化学平衡进行了分析计算。本方法适用于存在大量化学反应的气态物系。
In this paper, the calculation method of the chemical equilibrium of complex gaseous compounds containing inert components is deduced in detail using the principle of free-enthalpy minimum. Improved W-J-D method and Lagrange multiplier method. The chemical equilibrium of natural gas steam reforming to syngas is also analyzed and calculated. This method is suitable for gaseous material systems with a large number of chemical reactions.
