Selective dielectric heating using the influence of a coupling medium such as water can lead to the formation of combined temperature-mass transport pulses moving through a packed bed. Depending on the dielectric and sorption properties of the material, these so-called thermo-chroma-tographic pulses (TCP) can cause large temperature differences between the starting temperature and the peak temperature in the pulse. The impregnation of porous substances with various salts was shown to be a simple methodfor improving material properties leading to the formation of stable TCP. This procedure was proven to only slightly reduce the specific surface area and the sorption capacity towards organic compounds of the investigated sorbents. Consequently, a wide spectrum of silica gels, zeolites and porous alumina can be applied as matrices for TCP-based processes in chemical engineering and environmental technology.

盐浸渍对介电加热引发热色谱脉冲的影响

使用耦合介质（例如水）的影响进行选择性介电加热可导致形成组合的温度-质量传输脉冲，该脉冲移动通过填充床。根据材料的介电和吸附特性，这些所谓的热色谱脉冲 (TCP) 会导致脉冲的起始温度和峰值温度之间存在较大的温差。研究表明，用各种盐浸渍多孔物质是一种改善材料性能从而形成稳定 TCP 的简单方法。事实证明，该程序仅略微降低了所研究的吸附剂的比表面积和对有机化合物的吸附能力。因此，广泛的硅胶，
