Abstract
Infrared (IR) microimaging is employed for selectively recording two-dimensional plots of the individual distributions of the components n-hexane (nC6) and 3-methylpentane (3MP) over a single crystal of zeolite ZSM-5 during mixture adsorption. At a pressure change from 0 to 0.02 mbar, the scenario of “overshooting” is observed, with the concentration of nC6 temporarily exceeding its equilibrium value. After the next pressure step from 0.02 to 2 mbar, 3MP is progressively driven out of the pores, in parallel with an increase in nC6 concentration. The IR microimaging results are corroborated by grand canonical Monte Carlo simulations, which help explain the peculiarities of mass transfer by providing visual representations of the distribution and packing densities of the guest molecules in the pores.
期刊介绍：
Die Chemie Ingenieur Technik ist die wohl angesehenste deutschsprachige Zeitschrift für Verfahrensingenieure, technische Chemiker, Apparatebauer und Biotechnologen. Als Fachorgan von DECHEMA, GDCh und VDI-GVC gilt sie als das unverzichtbare Forum für den Erfahrungsaustausch zwischen Forschern und Anwendern aus Industrie, Forschung und Entwicklung. Wissenschaftlicher Fortschritt und Praxisnähe: Eine Kombination, die es nur in der CIT gibt!
