The Role of Dielectric Properties in Microwave-Assisted Pyrolysis of Forest Biomass

Öz

Microwave-assisted pyrolysis (MAP) is a promising thermochemical conversion method for converting forest/lignocellulosic biomass into valuable bio-based products. The efficiency of MAP strongly is governed by the dielectric properties of the feedstock, particularly the dielectric constant (ε′), dielectric loss factor (ε″), and loss tangent (tan δ), which govern how effectively microwave energy is converted into heat. This study focuses on the dielectric properties of different types of forest biomass (hardwoods, softwoods) and their effects on microwave pyrolysis efficiency and yield. The study also aims to show how the usage of catalysts, additives, and feedstock blending affects product selectivity, heating rates, and product yield.
