Biorefinery has been prooved as a sound approach for the conversion of biomasses to raw chemicals integrating several processes ranging from fermentation to thermochemical treatments. Among them, pyrolysis represents a valuable tool for biomass conversion: as a matter of fact, high-quality oil with proprieties like a fuel can be recovered by fast processes run on lignocellulosic biomasses using different reactors designs and process parameters. In the same field, an innovative approach is represented by the use of microwaves as a heating source for pyrolytic conversion. Microwave (MW) induces very fast and volumetric heating but usually require a susceptor able to adsorb MW and dissipate heat after the interaction with the electromagnetic field. Microwave-assisted pyrolysis has been largely used for biomass conversion with a particular emphasis on the production of liquid fractions also known as bio-oils. It finds also a lot of applications as a source of chemicals such as pesticides, mixtures for chemical treatments or employed after purification procedures (i.e. extraction or a fractionating process to isolate the more interesting compounds present, such as acetic acid, levoglucosane, aromatics, and furans.
