宾夕法尼亚州立大学报告说，基于空位溶液理论的新关联改进了根据单组分吸附等温线数据对气体混合物吸附平衡的预测。与其他可用模型相比，新方法更通用、更容易应用且更准确。对于吸附系统，二元参数（吸附物和空位）是通过纯气体吸附数据与空位-溶液等温方程的回归获得的。然后，假设吸附物-吸附物相互作用可以忽略不计，则使用这些参数来预测多组分吸附平衡。宾夕法尼亚州立大学已经验证了两种不同类型的二元吸附系统的新相关性：O/sub 2/、N/sub 2/ 和 CO 在沸石 10X 上的混合物以及轻烃混合物在 Nuxit-AL 活性炭上。
The new correlation based on vacancy-solution theory, reports Pennsylvania State University, improves predictions of gas-mixture adsorption equilibria from single-component adsorption isotherm data. The new method is more general, simpler to apply, and more accurate than other available models. For an adsorption system, the binary parameters - adsorbate and vacancy - are obtained from regression of the pure-gas adsorption data with the vacancy-solution isotherm equation. These parameters are then used to predict multicomponent adsorption equilibrium, assuming that the adsorbate-adsorbate interactions are negligible. Penn State has verified the new correlation on two different kinds of binary adsorption systems: mixtures of O/sub 2/, N/sub 2/, and CO on zeolite 10X and mixtures of light hydrocarbons on Nuxit-AL activated carbon.
