Description: Solid biofuel generated by thermochemical processes such as torrefaction has been considered a bio-based fuel with improved energy content and combustion characteristics. This study was conducted to investigate the feasibility of converting meadowfoam (MF) and abyssinian (AB) oil-extraction byproducts to high-energy solid fuels. A microwave-assisted torrefaction process was employed based on a central composite design to study the importance of process parameters and to optimize the combinations of the factors (byproduct type, electromagnetic power (up to 600 W), residence time (up to 50 min), and initial moisture (up to 20%) on the quality attributes of the biofuel and the conversion yield. The results indicated that the source of the fuel, residence time, and electromagnetic power would be the more important parameters in controlling this thermochemical conversion. According to the energy and elemental analyses, both byproducts showed the potential of conversion to solid biofuel with approximately 20% more HHV (higher heating value) compared to the original materials.
