Computer Simulations of the Energetics and Siting of n-Alkanes in Zeolites
Open accessAbstract
The adsorption of the n-alkanes, ranging from butane to dodecane, in the zeolites silicalite and (all silica) mordenite has been studied in the zero coverage limit using computer simulations.The heats of adsorption, Henry coefficients, and distribution of the n-alkanes over the different zeolite channels are calculated.The calculated heats of adsorption are in good agreement with available experimental data.The calculated heats of adsorption in silicalite show a n unexpected alkane length dependence.The incremental heat of adsorption per carbon atom is larger for the longer alkanes than for the shorter alkanes.This observation is attributed to preferential adsorption of the longer alkanes in the straight channels of silicalite.Simulations of this type were made possible through the development of a novel Monte Carlo simulation technique which is orders of magnitude more efficient than the conventional simulation techniques.

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.
