报道了Na-丝光沸石和H-丝光沸石在几个温度下的吸附等温线，以及一系列高于其临界温度的气体吸附剂。使用多重平衡分析 (MEA) 方法对数据集进行分析 [Drago, R. S.；等人。 J. Am.化学。苏克。 1998, 120, 538−547。德拉戈，R.S.；等人。 J. Phys。化学。 B 1997, 101, 7548−7555]，生成每个过程的吸附平衡常数 (Ki)、容量 (ni) 和热力学参数（焓，ΔHi 和熵，ΔSi）。沸石丝光沸石中存在的有限孔径分布与 MEA 先前研究的无定形碳进行了有趣的比较 [Drago, R. S.;等人。 J. Phys。化学。 B 1997, 101, 7548−7555]。 MEA 对吸附物（特别是 N2、CO 和 Xe）与 Na−丝光沸石和 H−丝光沸石相互作用所收集的吸附数据的描述结果与其他文献报告（包括红外光谱研究和蒙特卡罗模拟）进行了比较，并进行了比较。
Adsorption isotherms are reported for Na−mordenite and H−mordenite at several temperatures with a series of gas adsorptives above their critical temperature. The data sets are analyzed with the multiple equilibrium analysis (MEA) method [Drago, R. S.; et al. J. Am. Chem. Soc. 1998, 120, 538−547. Drago, R. S.; et al. J. Phys. Chem. B 1997, 101, 7548−7555], which produces equilibrium constants (Ki), capacities (ni), and thermodynamic parameters (enthalpies, ΔHi, and entropies, ΔSi) of adsorption for each process. The limited pore size distribution present in the zeolite mordenite presents an interesting comparison to the amorphous carbons studied previously by MEA [Drago, R. S.; et al. J. Phys. Chem. B 1997, 101, 7548−7555]. The results of the MEA description of the adsorption data gathered for the interaction of an adsorbate (particularly, N2, CO, and Xe) with Na−mordenite and H−mordenite are compared to other literature reports (including infrared spectroscopic studies and Monte Carlo simulations), and go...
