In developing new adsorption separation processes, it is necessary to study both the equilibrium and dynamic adsorption properties of potential materials. Experimental determination of isotherms and dynamic breakthrough properties aid in the development of modeling new adsorption systems toward process development. Here, the equilibrium adsorption properties of a small‐pore zeolite, Na‐SSZ‐13, are studied for its natural gas separation potential. Using volumetric, gravimetric, and dynamic column breakthrough adsorption techniques, the adsorption properties of CO₂, CH₄, C₂H₆, H₂S, and H₂O are determined. High‐pressure breakthrough experiments demonstrate the mixed gas separation performance of Na‐SSZ‐13 in mixtures containing CO₂, CH₄, C₂H₆, and H₂S. Simulations of these breakthrough experiments show that ideal adsorbed solution theory adequately describes the mixed gas adsorption modeling for this zeolite. In gas mixtures containing both CO₂ and H₂S, there is an observed acid gas reaction that results in elution of carbonyl sulfide, COS.

酸性气体在SSZ-13沸石上的吸附：天然气应用中的平衡和动力学行为

在开发新的吸附分离方法时，有必要研究潜在材料的平衡和动态吸附特性。等温线和动态突破特性的实验确定有助于为过程开发建模新的吸附系统。在此，研究了一种小孔沸石Na‐SSZ-13的平衡吸附特性，以了解其天然气的分离潜力。使用体积，重量和动态柱穿透吸附技术，CO ₂，CH ₄，C ₂ H ₆，H ₂ S和H ₂的吸附特性O确定。高压突破实验证明了Na‐SSZ-13在含CO ₂，CH ₄，C ₂ H ₆和H ₂ S的混合物中的混合气分离性能。这些突破实验的模拟表明，理想的吸附溶液理论充分描述了该沸石的混合气体吸附模型。在同时包含CO ₂和H ₂ S的气体混合物中，观察到酸性气体反应，导致洗脱羰基硫COS。
