First Results of Waste Biomass Fast Pyrolysis in a Quartz Solar Drop Tube Reactor
Short Introductive summary
The Circular Fuels project, funded by the European Union (Horizon Europe) in partnership with nine organizations, seeks to produce SAFs from the pyrolysis of biowaste feedstocks by utilizing concentrated solar energy. Through advancements in renewable energy harvesting and technological innovation, the project aims to convert low-cost and abundant waste wood and agricultural residues into renewable bio-oil using solar-assisted fast pyrolysis. This approach eliminates combustion while simultaneously valorizing by-products, enhancing sustainability in biofuel production. The developed low-temperature solar-assisted drop-tube pyrolysis reactor at CNRS-PROMES (France) aims to reach a higher yield of bio-oil from the waste biomass by operating at an optimal reaction temperature of around 400-600 °C in a transparent quartz tube (direct solar heating). This paper presents a brief introduction to the reactor experimental set-up, instrumentation, followed by the experimental results from the first successful campaign of 2025.
