Abstract:

A lab-scale fluidized bed is setup and pyrolysis experiments are carried out.When temperature ranges from 400 to 700 ℃, the yields of solid residue, bio-oil and syngas range from 36% to 18%, 19% to 30% and 9% to 42%, respectively, and the mass balance of pyrolysis ranges from 80% to 95%.At 400 to 700 ℃, the characteristics of bio-oil are similar and the heat value is about 10 MJ/kg.When the temperature is over 600 ℃, the yield of syngas increases approximately twice as much as that at 500 ℃.The yields of CO₂ and CO increase from 70 to 230 L/kg and 50 to 106 L/kg, respectively, while the yield of syngas only increases about 5% when the temperature increases from 600 to 700 ℃.The results indicate that the pyrolysis mechanism of waste paper is similar from 400 to 700 ℃, while the yield of syngas can be affected by secondary pyrolysis of bio-oil.
