Abstract By utilizing the specific influence of water adsorption on the dielectric loss factor and,
consequently, selective heating of the zeolite NaY in a radio-frequency (RF) electromagnetic field,
a hot zone moving through the packed bed can be realized initiated by water injection. While the
effect of water adsorption on RF heating and the phenomenon of the thermo-chromatographic
pulse (TCP) itself were described in a previous paper, the present study presents a detailed
model for the description and explanation of this effect. It involves the complex dependence of
dielectric loss on temperature and moisture content, a diffusion model considering both hopping
and Knudsen mechanisms and a power balance for a representative segment of the packed bed.
The developed model was successfully applied to adequately describe various experimental
situations observed for selective RF heating in a NaY zeolite bed.
