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,计算在给定温度和压力下混合气体中每一组分的平衡吸附量。文章应用空穴溶液气体吸附FHVSM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。研究结论表明,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;在分子筛上的吸附量相当可观,且吸附相的组成与在自由相的组成存在明显的差异。
Adsorption of mixed gas not only is related to the temperature and pressure, but also changes as the gas composition changes, because exists the so-called 'Competing adsorption phenomena'. The adsorption model of mixed gas is to calculate the equilibrium adsorbing volume for each component of the mixed gas under the given temperature and pressure by using the adsorption isotherms of pure component or bi-component gas. Applying FHVSM model of gas adsorption, taking the adsorption equilibrium of 2 dual gas mixtures as example, the simulation calculation of the adsorption equilibrium for the gas mixtures are completed after the parameters regressing calculation of adsorption isotherms for each pure component. The study result shows the FHVSM model of gas adsorption can be used to describe the adsorption equilibrium of gas mixtures. The adsorption volume is quite big on the molecular sieve. And the composition of adsorption phases defers from that of free phases obviously.
