Adsorption of CO2, N2, and O2 on Natural Zeolites
Abstract
Pressure swing adsorption (PSA) and temperature swing adsorption are potential techniques for removing CO 2 from high-pressure fuel gas streams. Natural zeolites are suitable candidate sorbents for use in the PSA process. Studies of volumetric gas adsorption of CO 2, N 2, and O 2 on three natural zeolites, with different major cations, were conducted at 25 °C up to a pressure of 300 psi (2 × 10 6 Pa). Preferential adsorption of CO 2 was observed with all three zeolites. The natural zeolite with the highest sodium content and highest surface area showed the highest CO 2 adsorption capacity. Competitive gas adsorption studies also showed that the zeolite with the highest sodium content gave the best separation of CO 2 from the gas mixtures. Contact time did not affect the extent of adsorption of the zeolites. Temperature-programmed desorption studies indicated that the majority of the physically adsorbed CO 2 was desorbed at room temperature, while some strongly bound CO 2 was desorbed at 115 °C.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
