Deviation from Arrhenius behaviour of rate of intercage diffusion in Zeolite Y1

Abstract

Rate of intercage diffusion (k c ) along with rate of cage visits (k v ) and diffusion coefficient (D) of sorbates in zeolite Y have been calculated. We show that as a consequence of the dependence of rate of intercage diffusion on short-time behaviour, significant deviation from the Arrhenius behaviour at suffciently high temperatures occurs.
