摘要： 以起泡体积、半衰期为指标,研究了疏水基链长对烷基糖苷(APG)形成CO2泡沫的性能。结果表明,APG的疏水链越长泡沫越稳定,APG0814的起泡性能优于其他链长APG。研究了质量浓度对APG0814泡沫性能的影响,当APG0814的质量浓度为3 g/L时,形成的CO2泡沫最稳定;质量浓度越高,起泡体积越大。通过物理模拟实验研究了气液比、实验压强对APG0814形成的CO2泡沫降低气、水流度的影响,结果表明,气液比为2∶1时,CO2、水流度降低幅度最大;实验压强越高,CO2、水流度降低幅度越大。

Abstract: The performance of CO2 foam formed by alkyl polyglycoside (APG) with different alkyl chain length were studied with foam volume and half-life as the criterion indices.Results indicate that the longer the hydrophobic chain length of APG,the higher stability of the foam.The foaming performance of APG0814 is superior to that of other APGs.The influence of mass concentration of APG0814 on the foaming performance was examined.The CO2 foam formed by APG0814 at 3 g/L shows the highest stability.The higher mass concentration,the larger foam volume.Physical simulation experiments were carried out to study the influence of the gas-liquid ratio and the experimental pressure to the mobility decreasing of CO2 and water for the CO2 foam formed by APG0814.Results indicate that when the gas-liquid ratio is 2∶1,the range of mobility reduction of CO2/water achieves the highest.The amplitude for reduction of CO2/water mobility increases with the increase of pressure.

Key words: foam, alkyl polyglycoside, carbon dioxide, half-life, mobility
