    摘要:

    采用微波熱解反應(yīng)器系統(tǒng)與氣相色譜和質(zhì)譜分析儀以及等溫吸附儀等研究了NaCl、K2CO3、MgCl2的添加對(duì)農(nóng)業(yè)廢棄物棉稈微波熱解特性的影響。結(jié)果表明，3種金屬鹽添加劑均使液體產(chǎn)物產(chǎn)率下降，固體產(chǎn)物產(chǎn)率增加，且添加劑的加入對(duì)簡(jiǎn)化生物油組分以及提高生物油品質(zhì)效果顯著，產(chǎn)物中酚類(lèi)物質(zhì)含量明顯降低，乙酸的相對(duì)含量由11.87%提升至37.57%，固體焦炭的表面孔隙結(jié)構(gòu)也得到了明顯改善。

    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.
