摘要
在提出多孔介质中自由气相与吸附相的二相相平衡计算假设条件之后 ,应用空穴溶液气体吸附FHVSM模型建立了吸附相与自由气相之间的两相相平衡计算模型 ,针对一个二元气体混合物吸附平衡例子 ,在完成其纯组分吸附等温线的参数回归计算之后 ,完成了气体混合物吸附平衡模拟计算。研究结果表明 ,空穴溶液气体吸附FHVSM模型能用于描述气体混合物吸附平衡。
The vacancy solution theory is presented on the Gibbss adsorption lsothermal equation.It considers that the adsorbent surface is consisted of the vacancy and the adsorption potential,and that the adsorption phase is the solution,which contains the vacancy,the adsorption potential and the adsorbed gas molecule.Following presenting the hypothesis model of the freedom gas and the adsorption phases equilibrium in the porous media,the two phases equilibrium calculation model is set up in this paper by using the Flory Hugging vacancy solution model of gas adsorption.For an example of the dual gas mixture adsorption equilibrium,the adsorption equilibrium simulation is completed after regressing the parameters of the pure component adsorption isotherm.The research result shows that the Flory Hugging vacancy solution model can be used to describe the gas mixture adsorption equilibrium.
