巢湖蓝藻与农业废弃物共热解制取生物质油研究
|
摘要
采用蔗渣、玉米秸秆和棉花秸秆3种废弃物与蓝藻进行混合共热解试验,考察废弃物的加入对蓝藻热解液体产率及组分的影响。结果表明:添加3种废弃物均使共热解液体产率呈下降趋势。当蓝藻与废弃物以1∶1混合共热解时,以蓝藻和玉米秸秆共热解液体产率最高,为61.8%,且除苯酚类以外,液体产物组分与单一蓝藻热解产物组分相近,含氮化合物含量明显降低,相对含量由18.49%降至8.15%。与其它2种废弃物相比,蓝藻与玉米秸秆在适当比例下的共热解有利于改善热解油品质。
The co-pyrolysis of algae and three kinds of wastes such as bagasse,corn,cotton stalk were studied. The yield and chemical compositions of liquid product were focused in the experiment. The results showed that three kinds of wastes additives made the yield of liquid product decrease. When the ratio of algae and corn stalk was 1 ∶ 1,the liquid yield can be maximal reached to 61. 8%.The components of liquid product from algae and corn co-pyrolysis were close to the algae pyrolysis product compositions. Nitrogen compounds were greatly lower in the product and the peak area percentage decreased to 8. 15% from 18. 49%. Compared to the other two kinds of wastes,the co-pyrolysis of algae and corn in proper ratio can improve the quality of bio-oil effectively.
