| 摘 要： | 为提高蔗渣的综合利用效率,采用催化剂定向的蔗渣微波辅助裂解技术,系统探讨了影响糠醛得率的工艺参数,以及裂解残余生物焦经过中和后作为土壤改良剂的使用效果.实验结果表明:当微波裂解功率为900W,添加蔗渣干重的10％的磷酸,1％的硫酸,100％的红壤黏粒时,糠醛的得率最高,为蔗渣干重的4.5％,该处理生物焦具有多孔性,经傅里叶红外光谱分析表明存在有机磷酸酯键和Si-C共价键,表明裂解过程中形成有机无机复合物.生物焦经中和后,对于红壤的改土增产效果显著:盆栽大豆出苗率、株高、地上部干重、地下部干重、根瘤数量、单株结荚数分别比对照提高了33.3％、24.3％、115％、60％、326％和267％.盆栽白菜抗旱存苗率、株高、鲜重、地上部干重、根重分别比对照提高2.3、0.36、12.3、6.8和5.5倍. |

| Abstract: | In order to improve the synthetical utilization efficiency of bagasse, microwave assisted and catalyst oriented pyrolysis technology were adopted to investigate the process parameters which affect the furfural yield and the properties of the corresponding biochar. Biochars was then neutralized and served as soil amendent. The results showed that: the highest yield of furfural, 4.5% of dry bagasse mass was achieved when pyrolysis power was 900 W, phosphoric acid was 10%, sulphuric acid was 1% and the red earth clay was 100% of the dry bagasse mass. It was testified by FTIR that there exsisted organic phosphate bond and Si-C covalent bond in this porous biochar obtained under this experimental condition. The fertility of red soil was significantly improved by using the neutralized biochar: soybean planting percentage, plant height, dry weight of aerial part, dry weight underground part, root nodule number, pod number per plant were increased by 33.3%, 24.3%, 115%, 60%, 326% and 267% in the soybean pot culture test repsectively. Drought survival rate of Chinese cabbage seedlings, plant height, fresh weight and dry weight of aerial part, the fresh weight of underground part were increased by 2.3, 0.36, 12.3, 6.8 and 5.5 times, repsectively. |
