Abstract

The article presents the results of theoretical and experimental studies comparing the thermal degradation of high moor sphagnum peat in the process of pyrolysis (thermolysis) initiated by convenient thermal and microwave exposure. Based on modeling using the commercial software package CST Studio Suite, reactor designs have been developed that allow for a correct comparison of these processes under identical conditions. Comparative experiments conducted on the basis of reactors with various thermal sources have demonstrated the advantages of microwave pyrolysis, which allows for “instantaneous” and volumetric heating of the product and its deeper processing with high energy efficiency. The results of peat processing under different thermal effects and the yield of pyrolysis reaction products are discussed.
