| 摘 要： | 研究了温度对稻草流化床快速热解中热解油产率的影响,利用GC/MS、FT-IR考察了不同热解温度(300℃~600℃)及冷凝温度(22℃、-4.4℃)下,稻草经过热解所获得的热解油组成。结果表明,稻草在400℃热解温度下可获得最高热解油产率43.1%;冷凝温度对热解油的品质有较大影响,降低冷凝温度能够增加热解油中有机物的含量,热解油中的水分含量随之降低,同时热解油的热值也随之得到提高。

| Abstract: | The present work focused on the effect of pyrolysis temperatures on the yield of bio-oil from fast pyrolysis of straw in a fluidized bed reactor. The chemical compositions of bio-oil, obtained at 300 ℃～600 ℃ coupling with condensation at 22 ℃ or -4.4 ℃, were examined by GC/MS and FT-IR. The results show that the highest bio-oil yield of 43.1% is obtained at 400 ℃. The condensation temperature significantly affects the quality of bio-oil. Lower condensation temperature facilitates increasing of its heat value and the content of organics, and consequently decreasing the concentration of water. Based on the present result, the subsequent technology could be flexibly set up to meet the objective requirements and obtain operation parameters to optimize the pyrolysis process. |
