“…Figure shows the morphology of the adsorbed layer on mica of four cationic surfactants used in this study. No alkylpyridinium surfactants have previously been examined at the solution−solid interface by AFM, but numerous adsorption isotherms have been determined on a range of substrates. , AFM images of the pyridinium surfactants TPC, CPC, and HFDePC all show stripes, implying adsorbed cylinders. Repeated attempts to image DPC were unsuccessful.…”

The adsorbed layer structure of tetradecylpyridinium, hexadecylpyridinium, heptadecafluorodecylpyridinium, and tetradecyltriethylammonium chloride and their mixtures on mica has been determined by AFM imaging. In addition, the composition of the mixed adsorbed layers has been measured, showing a significant surface enrichment of the pyridinium surfactants, particularly the partially fluorinated species. Shape transitions in the adsorbed layer are correlated with surface and bulk compositions and explained by consideration of the adsorption mechanism.

“…The adsorption of some cationic surfactants was studied previously using various adsorbents such as silica [19,20], quartz [21], zeolite and clinoptilolite [22], rutile [23], cellulose [24], carbon black [25], coal [26] and activated carbon [27][28][29]. However, we have not met any study for the adsorption of cationic surfactants using the ACC adsorbent in literature.…”

The Impact of Ionic Liquid and Nanoparticles on Stabilizing Foam for Enhanced Oil Recovery

et al. 2018

One of the commonly used tool in enhance oil recovery (EOR) is nitrogen foam flooding. The sweeping efficiency is largely determined by the foam stability. Recently the study on using nanoparticle, alone or with other chemicals, to stabilize foam has emerged in several fields of foam application. In this study, we use a combination of physicochemical tools to analyze the synergetic effect of ionic liquid cetylpyridinium chloride (CPC) with nanoparticle in foam flooding of EOR. Two different nanoparticles (NPs), one hydrophilic and the other hydrophobic, are compared in terms of sweeping efficiency. It was found that CPC with hydrophilic NPs is much more effective in foam flooding residue oil than with hydrophobic NPs. This may be due to the difference in CPC orientation on NP surfaces, thus affecting the surface properties including surface tension, elasticity and contact angle. Consequently the stability of foam, which underpins the oil displacement efficiency in EOR, is influenced. The possible interaction and mechanism between CPC, NP and oil are discussed while considering the contribution from reduction of drainage rate, higher particle adsorption energy, and higher surface elasticity. Understanding the differential roles of hydrophilic and hydrophobic nanoparticles in ionic liquid stabilized foam as well as physical mechanism underpinning their specificity could help facilitate the development of new green nanomaterial in the application of EOR.
