3-5-3 半導体マイクロ波加熱装置によるサセプターフリーなバイオマスの急速熱分解

抄録

Pyrolysis of biomass produces useful compounds such as biochar, bio oil and syngas, but low thermal conductivity of biomass is a big issue to achieve efficient heat transfer. In this study, microwaves with high electric field density are input into a single mode cavity using high coherence microwaves generated by a semiconductor oscillator. Pyrolysis of cellulose and rise straw were performed by directly heating biomass wiuthout using microwave susceptor. The maximum heating rate of rice straw attained 330°C/sec by using the present microwave set-up.
