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.

将热色谱脉冲 (TCP) 建模为射频 (RF) 诱导的选择性加热效应

摘要 利用水吸附对介电损耗因子的特殊影响，从而在射频 (RF) 电磁场中选择性加热沸石 NaY，可以通过注水启动热区穿过填充床。 . 虽然水吸附对 RF 加热的影响和热色谱脉冲 (TCP) 本身的现象在之前的一篇论文中有所描述，但本研究提供了描述和解释这种影响的详细模型。它涉及介电损耗对温度和水分含量的复杂依赖性、考虑跳跃和 Knudsen 机制的扩散模型以及填充床代表性部分的功率平衡。
