NEGATIVE SYNERGISTIC EFFECT OF AMINO IONIC LIQUID SUPPORTED ACTIVATED CARBON ON CO₂ ADSORPTION PERFORMANCE

摘要

摘要: 通过三亚乙基四胺与L-乳酸的酸碱中和反应合成[TETA][L]离子液体，并将不同质量分数的离子液体负载到椰壳活性炭中，利用傅里叶红外光谱仪、X射线衍射仪、全自动比表面和孔径分布分析仪研究[TETA][L]离子液体浸渍对椰壳活性炭微观结构以及CO₂吸附性能的影响。结果表明：离子液体与活性炭之间的相互作用会导致石墨微晶细晶化，对活性炭的结构稳定性有不利影响，而离子液体对椰壳活性炭孔隙结构的"堵塞式"填充，导致复合材料CO₂物理吸附性能显著下降和CO₂化学吸附性能有限增加，这是造成复合材料CO₂总吸收性能显著降低的根本原因，且离子液体在活性炭中呈现了一种由小孔径到大孔径的"阶梯式"填充行为。

Abstract: [TETA] [L] ionic liquid was synthesized by the acid-base neutralization reaction of triethylenetetramine and L-lactic acid, and different mass fractions of ionic liquid were loaded into coconut shell activated carbon. The effects of ionic liquid impregnation on the microstructure and CO₂ adsorption performance of coconut shell activated carbon were investigated by FTIR, XRD and automatic specific surface and pore size distribution analyzer. The results showed that the interaction between ionic liquid and activated carbon led to the fine crystallization of graphitized microcrystals, which adversely affected the structural stability of activated carbon, while the "plugging" filling of the pore structure of coconut shell activated carbon by ionic liquid led to the significant decrease of CO₂ physical adsorption performance, and limited the increase of CO₂ chemisorption performance of the composite, which was the root cause of the significant decrease in the total CO₂ absorption performance of the composite. And ionic liquid in activated carbon showed a "step" filling behavior from small pore size to large pore size.
