文摘分子筛材料在吸附分离领域具有重要的应用价值,吸附质在分子筛中的晶内扩散行为是评价其吸附分离效果的重要依据之一。零长柱方法(zero length column,ZLC)可准确评价晶内扩散行为,但经典的ZLC实验利用鼓泡法获得不同分压的有机蒸气,无法适用于饱和蒸气压较低的吸附质,同时起泡器温度的微小变化也会影响蒸气压。鉴于此,基于反气相色谱(inverse gas chromatography,IGC),结合微量注射泵搭建了一套IGC-ZLC装置评价晶内扩散行为,以饱和蒸气压较低的正辛烷作为吸附质分子,ZSM-5作为吸附剂,在不同分压、载气流量、进样体积和温度下验证了改进IGC-ZLC方法的准确性,同时对比了正己烷、正庚烷、正壬烷、异辛烷和环辛烷的扩散行为,为在极端场景下测定晶内扩散系数提供了一种潜在的新方法。
