Overview

Randomized trial demonstrates improved biomass pyrolysis with solar integration, indicating scalable CO2 reduction potential.

Key Points

  • 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.
