Abstract

Biomass is the only sustainable, renewable, and environment-friendly source of organic carbon that we now obtain from fossil resources. Biomass can be converted to various fuels and chemicals by different biochemical and thermochemical processes. The conventional methods of conversion have several disadvantages of low energy efficiency, poor heat transfer, low carbon utilization, etc. Increasing the efficiency of biomass conversion to obtain more value-added hydrocarbons is a challenging task. In this regard, microwave energy can efficiently be used for different biomass pretreatment and conversion processes with higher energy efficiency compared to the conventional processes. The selective cleavage by molecular interactions would enable the complete organic content utilization thereby producing bulk/specialty chemicals/fuels. Microwave pyrolysis can be used for diversified feedstocks without any energy-intensive pretreatment steps like drying and crushing. Compared to conventional pyrolysis, microwave pyrolysis produces better-quality bio-oil, gas, and biochar. The chapter aims to provide an updated comprehensive review on the usage of microwave energy for the biomass pyrolysis.
