Unravelling the mechanisms of microwave pyrolysis of biomass

John Robinson et al.

Summary: This study establishes a new mechanism for microwave pyrolysis of biomass through empirical observations and mass transfer simulations. It demonstrates that microwave heating can significantly reduce pyrolysis temperatures for cellulose and hemicellulose, with dielectric properties varying based on heating rate. The study also identifies liquid-phase water as a key driver for the observed differences in microwave pyrolysis process.
