  氟碳表面活性剂N-（2-羟丙基）全氟辛烷酰胺在水溶液中胶束形成的研究

  摘要：

  通过表面张力，动态光散射（DLS），等温滴定量热法（ITC）和耗散粒子动力学（DPD）模拟研究了碳氟化合物表面活性剂N-（2-羟丙基）全氟辛烷酰胺在水溶液中形成的胶束。通过表面张力测量，研究了表面张力降低的有效性，最大表面过量浓度和每个表面活性剂分子在空气/水界面处所占的最小面积。在不同温度下的临界胶束浓度（cmc）和一系列热力学参数（ΔG m 0，ΔH m 0，ΔS m 0，ΔG ads 0，Δ ħ米甲和Δ Ç p米0胶束化）进行了评价。热力学参数表明，胶束的形成是由熵驱动的。ITC和DLS也证实了胶束的形成。另外，进行了DPD模拟以模拟胶束形成的整个过程，以使胶束形成得到更好的理解。

  The disclosure discloses an ultra-dry three-phase flue gas foam for oil-gas fields and preparation method thereof. The ultra-dry three-phase flue gas foam is produced by a gas phase, a liquid phase and a solid phase; the gas phase is a flue gas; the foaming solution is an aqueous solution of a surfactant, a pH adjuster, and an inorganic salt; the solid phase is a composite of fly ash and nano silica; the foam quality is 90%-99%. The solid phase foam stabilizer is a compounded system of fly ash particles and nano silica particles, which is not only low in cost but also can form a stable solid particle adsorption layer on the foam film. Thus the instability of the foam such as film rupture, gas diffusion and bubble aggregation can be greatly reduced, and the stability of the foam can be effectively improved.

  本发明公开了一种用于油气田的超干三相烟气泡沫及其制备方法。超干三相烟气泡沫由气相、液相和固相制备而成；气相为烟气；发泡液为表面活性剂、pH调节剂和无机盐的水溶液；固相为粉煤灰和纳米二氧化硅的复合体系；泡沫质量为90%-99%。固相泡沫稳定剂是粉煤灰颗粒和纳米二氧化硅颗粒的复合体系，不仅成本低，而且能在泡沫膜上形成稳定的固体颗粒吸附层。因此，可大大降低泡沫的不稳定性，如膜破裂、气体扩散和气泡聚集等，有效提高泡沫的稳定性。
