Measurement of Dielectric Characteristics of Bulk Cellulose-containing Materials at a Frequency of 2.45GHz

A method has been developed for studying the dielectric parameters of materials of plant origin i.e., high and low-lying peat, microcrystalline cellulose, lignin, as well as peat processing products using microwave radiation at a frequency of 2.45GHz. Based on this method, the dependences of the reflection coefficient on the thickness of the layer of the material under study were obtained. As a result, the values of dielectric constant and loss tangent of plant materials of various types were determined. These studies are focused on the development of complexes for microwave processing of organic fuel in the process of pyrolysis.
