This work aims to develop a continuous biomass pyrolysis process using solar-thermal energy, enhancing product control and scalability.
Developed an inclined tubular reactor for continuous operation.
Characterized hydrodynamics with particle image velocimetry and validated using CFD simulations.
Analyzed food waste pyrolysis at varying temperatures and reactor conditions.
At 600 °C and a reactor length of 3.5 m, devolatilization rates exceed tar-cracking rates by 2-3 orders of magnitude in optimal conditions.
Achieved a high liquid yield of approximately 48 wt% during pyrolysis.
Scale-up analysis predicts a capacity of 300,000 t yr −1, with avoided emissions of around 16,000 t CO2 yr −1.

Makkawi et al. (2026) studied this question.
