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.
在自行设计的流化床实验台上进行废纸热解实验研究.当热解温度从400 ℃升高到700 ℃时, 固体残渣产率从36%降低到18%, 而热解油、热解气产率分别从19%增加到30%和9%增加到42%.实验的质量平衡达到80%~95%.各温度下, 液体产物特性相似, 热值都为10 MJ/kg左右, 说明在此温度范围内, 热解反应机理相似.当反应温度从500 ℃提高到600 ℃以上时, 热解气产量几乎提高一倍, 其中CO2与CO产量分别从大约70 L/kg提高到230 L/kg和50 L/kg提高到106 L/kg;而温度从600 ℃提高到700 ℃时, 热解气产量仅提高5%.研究表明, 热解油的二次裂解会影响热解气产量.
