High-Temperature Low-Pressure Adsorption of Branched C5−C8 Alkanes on Zeolite Beta, ZSM-5, ZSM-22, Zeolite Y, and Mordenite
Abstract
Henry constants, low-coverage adsorption enthalpies, van't Hoff preexponential factors, and separation factors of C 5 −C 8 alkanes are determined on beta, ZSM-5, ZSM-22, mordenite, and Y zeolites at 473−648 K using tracer and perturbation chromatographic techniques. Three different adsorption behaviors were encountered depending on the zeolite type: (1) nonselective competitive adsorption of isoalkanes and n -alkanes inside the micropores (zeolite Y), (2) preferential adsorption of the n -alkanes over the isoalkanes inside the micropores (beta, ZSM-5 and mordenite), and (3) selective adsorption of the n -alkanes in the micropores and of the isoalkanes on the external crystal surfaces (ZSM-22). Linear and mono- and multibranched alkanes can be separated on columns of ZSM-22 and beta zeolites.

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.
