| 摘 要： | 采用微波热解反应器系统与气相色谱和质谱分析仪以及等温吸附仪等研究了NaCl、K2CO3、MgCl2的添加对农业废弃物棉秆微波热解特性的影响.结果表明,3种金属盐添加剂均使液体产物产率下降,固体产物产率增加,且添加剂的加入对简化生物油组分以及提高生物油品质效果显著,产物中酚类物质含量明显降低,乙酸的相对含量由11.87％提升至37.57％,固体焦炭的表面孔隙结构也得到了明显改善.

| Abstract: | The scheme of biomass microwave pyrolysis reactor system, gas chromatography and mass spectrometry analysis instrument, temperature adsorption analyzer, and other analysis equipment were used to study the influence of cotton stalks with NaCl, K2CO3 and MgCl2 on microwave pyrolysis characteristics. The results showed that three kinds of metal salt additives made the yield of liquid product decrease and the yield of solid product increase. The introduction of additives can simplify the bio-oil components and improve the quality effect of bio-oil obviously. Phenolic compounds were significantly lower in the product and the peak area percentage of acetic acid increased to 37.57% from 11.87%, while the surface pore structure of solid coke was also significantly improved. |
