摘要

探究热解温度和原料质量混合比对木质纤维素类生物质与微藻共热解生物炭的产率、元素组成、表面形貌、热稳定性、孔隙分布、表面官能团组成及碳骨架结构的影响规律,并进一步揭示共热解过程中的协同效应及反应机理。结果表明,热解温度和原料质量混合比对共热解生物炭的产率以及理化结构均具有显著影响。生物炭产率随热解温度的升高而下降,并随微藻质量混合比的增加而增大。共热解生物炭的产率（质量分数）可达41.51%,相较于木质纤维素单独热解生物炭提高23.5%。木质纤维素与微藻共热解过程存在显著的协同效应,协同效应能够增大生物炭的产率,且显著促进C元素和N元素在生物炭中富集。热解温度的升高会促进生物炭中吡啶-N向季-N转化。微藻质量混合比的增加会增大生物炭的无序化程度和芳香化程度,微藻产生的含氮挥发分会与木质纤维素上的含氧官能团发生显著的美拉德反应,并进一步发生环化反应和缩聚反应生成富氮生物炭。

Abstract

In this study, the effects of pyrolysis temperature and lignocellulosic biomass/microalgae blending ratios on the yield, elemental composition, surface morphology, thermal stability, pore structure, surface functional group distribution and carbon skeleton structure of biochar derived from lignocellulosic biomass and microalgae co-pyrolysis were systematically investigated, and the synergistic effect and reaction mechanism during the co-pyrolysis process were further revealed. The results show that pyrolysis temperature and biomass/microalgae blending ratios had significant influence on the yield and physicochemical structure of co-pyrolysis biochar. The biochar yield decreases with rising pyrolysis temperature, and increases with higher microalgae blending ratios. The yield of co-pyrolysis biochar can reach as high as 41.51%, which is 23.5% higher than that of individual biomass biochar. The co-pyrolysis process of microalgae and lignocellulosic biomass exhibits a significant synergistic effect, which can enhance the yield of biochar and significantly promote the enrichment of C and N elements in biochar. The increase of pyrolysis temperature facilitates the conversion of pyridine-N to quaternary-N in biochar. With the increase of the microalgae blending ratios, the disorder degree and aromaticity of biochar is enhanced. The nitrogen-containing volatile produced from microalgae can react with the oxygen-containing functional groups on biomass through Maillard reaction, which further experience cyclization reactions and polycondensation reactions to form nitrogen-rich biochar.
