(320ac) Intracrystalline Diffusivities of Linear Paraffins in Zeolite Beta Using Zlc

BETA zeolite is an aluminosilicate with large micropores, polymorphous and three-dimensional structure with 12-membered rings in its framework. In this study we present measurement results of intracrystalline diffusivities of linear paraffins (C6-C10) in BETA zeolite using the ZLC method. The influences of desorption flow rate and temperature were evaluated. The diffusivity values were estimated using a Fickian mass transfer model that showed good agreement with the experimental desorption curves.
