Abstract
To study the process of biomass-based pyrolytic polygeneration and its mechanism in depth, the pyrolysis of cotton stalk was investigated in a packed bed, with focus on the evolution of the chemical and physical structures of the solid, liquid and gaseous products. The evolution of product characteristics could be good explaining the process mechanism of biomass pyrolysis. A relationship between the pore distribution of solid products and the fused aromatic rings system revealed by Raman analysis might be exist and need to quantify in further study. Regarding the optimum conditions for obtaining high-quality pyrolytic products from the polygeneration system, the optimum temperature is 550-750°C, with a higher calorific value of the obtained charcoal (≈ 28 MJ/kg) and a higher surface area (>200 m(2)/g). Meanwhile, the calorific value of the gas reaches 8-9 MJ/m(3) and the liquid oil would be used as a platform product in biorefinery. CrownEntities:
