摘要： 混合气体吸附不仅与温度、压力有关。而且随气体组成而变化、存在所谓竞争吸附现象。 混合气体吸附模型就是应用纯组分或双组分气体吸附等温线,可计算在给定温度和压力下混合气体中每- 组分的平衡吸附量。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.针对二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。不仅能用于烃类气体混合物吸附平衡模拟计算.而且能用于非烃类气体混合物吸附平衡模拟计算。

Abstract: Gas mixture adsorption is related to temperature and pressure, also there exists the competing adsorption phenomenawith the change of gas composition.The gas mixture adsorption model can be used to calculate the adsorption equilibriumquantity of each component of the gas mixture at certain temperature and pressure by using pure component or bi-component gasadsorption isotherm. The two-phase equilibrium calculation model with the adsorption phase and freedom gas phase is developed .using Flory Hugging Vacancy Solution Model(FHVSM)of gas adsorption.For two samples of dual gas mixture adsorptionequilibrium, the adsorption equilibrium simulation calculation is completed after regressing the parameters of the pure componentadsorption isotherm. The studied result shows that FHVSM can be used to describe the gas mixture adsorption equilibrium andsimulation calculations of adsorption equilibrium for both hydrocarbon gas mixture and non-hydrocarbon gas mixture.
