Temperature programmed desorption of n-hexane and n-heptane from MFI and FAU zeolites
Source abstract
Abstract
TPD studies of n-hexane and n-heptane from NaX, Y and ZSM-5 (Na+ or H+ exchanged) in the experimental system with a TCD detector were performed, using pure He or He/n-alkane mixture as a carrier gas. The TPD profiles with one desorption peak for Y and two peaks for ZSM-5, measured using He/hydrocarbon mixture, were similar to the previously reported equilibrated thermodesorption results. TPD profiles were accurately fitted with a model based on the equilibrium control of the desorption and the adsorption functions derived from the Langmuir or dual site Langmuir isotherms.
