The project B05N In-situ determination of heating and phase changes in microwave heated packed bed reactor (Barowski/Vorhauer-Huget) considers electromagnetic wave propagation with material-dependent reflection, transmission and absorption in cases of strongly coupled changes of dielectric properties with temperature and composition. For this purpose, a novel radar-based measurement setup will be developed in cooperation with B01 for processes up to max. 1000°C. The significant novelty of this measurement technique will be the ability to use it in-situ under high-temperature conditions inside the microwave reactor built in FP1. The detected dielectric changes will provide time-resolved correlations for local temperature and composition changes. Its functionality will be demonstrated for phase changes in wood together with B04. The impact of internal heat sources (direct volumetric heating by microwaves) on heat transfer coefficients will be investigated together with B02.
