in the ASAP-2010 are accurate to <0.2% for the pressure range of 0-1 atm. The sample weights were obtained using a digital laboratory balance which is accurate to ± 0.01 g. The isotherm measurements and the samples themselves were found to be highly reproducible. Results and Discussion All samples are identified according to the type of zeolite, the number of charge compensating cation(s) present in a unit cell, and the Si/Al ratio. For example Li86-X- 1.25 refers to an X-type zeolite with Si/Al = 1.25 which has been fully exchanged to contain 86 Li+ cations per unit cell. The sample Li94.2Na0.7Ag1.1-X-1.0 refers to an X-type zeolite with Si/Al = 1.0 which contains, on average, 94.2 Li+, 0.7 Na+, and 1.1 Ag+ (or other forms of Ag) per unit cell, as determined from the neutron activation (NA) and ICP- MS analyses. Analytical Characterization. As mentioned earlier, the samples were compositionally characterized using neutron activation analysis (NAA) and inductively coupled plasma mass spectroscopy (ICP-MS). Results of these analyses are given in Table 1. The unit cell compositions for those analyzed samples are given in Table 2. Adsorption Isotherms for Fully Exchanged Li and Ag Zeolites. Figure 2 shows the N2, O2 and Ar adsorption isotherms, measured at 25 C, for Li94.5Na1.5-X-1.0 after vacuum dehydration at 350 C. This zeolite is used in adsorptive air separation because of its very high N2 capacity and very favorable N2:O2 selectivity (approximately 6:1 at 1 atm) as well as its N2 isotherm linearity. 56PDF Image | PSA USING SUPERIOR ADSORBENTS
