application of surfactant modified kono-boue clay nanoparticles in oil recovery

Sodium dodecyl sulphate (sdsodium dodecyl sulphate (sds) mediated kono-bono (kb) clay nanoparticles (nps) applied in enhanced oil recovery (eor) have been investigated for the first time. this was done using synthesized kb clay nps as a control and sds-treated kb clay nps experiments in a micro model to determine the oil recovery rate. the samples were prepared by dissolving 15 g of kb clay in a mixture of 450 ml of de-ionized water and 150 ml of varying sds concentrations, magnetically stirred, dried at 110 °c for 90 minutes, and further calcined at 900 °c in a muffle furnace for 120 minutes. the samples were characterized with fourier transform infrared (ft-ir) spectroscopy, scanning electron microscopy (sem), x-ray fluorescence (xrf), and x-ray diffraction (xrd), respectively. ft-ir analysis indicated characteristic bending vibrations of al-oh bands at 698 cm-1 and stretching modes at 780, 1056, and 3655 cm-1 for (si-o and al-mg-oh) bands, respectively. sem micrographs showed surfaces with varying platy polycrystalline particle sizes, while xrf results identified the clay as kaolinite with silicate and alumina > 30 and 16%, respectively. the flooding experiment revealed that the sds-mediated kb clay nps (8.33 mm sds) gave the highest total oil recovery of 66.25 % at 0.10 wt. %. optimizing oil recovery at 8.33 mm by varying concentrations of kbc2 at 0.05, 0.10, 0.15, 0.20, and 0.25 wt. % gave a remarkable oil recovery rate of 85.27% at 0.15 wt.%. thus, 0.15 wt. % kbc2 is recommended for application in oil recovery.s) mediated kono-bono (kb) clay nanoparticles (nps) applied in enhanced oil recovery (eor) have been investigated for the first time. this was done using synthesized kb clay nps as a control and sds-treated kb clay nps experiments in a micro model to determine the oil recovery rate. the samples were prepared by dissolving 15 g of kb clay in a mixture of 450 ml of de-ionized water and 150 ml of varying sds concentrations, magnetically stirred, dried at 110 °c for 90 minutes, and further calcined at 900 °c in a muffle furnace for 120 minutes. the samples were characterized with fourier transform infrared (ft-ir) spectroscopy, scanning electron microscopy (sem), x-ray fluorescence (xrf), and x-ray diffraction (xrd), respectively. ft-ir analysis indicated characteristic bending vibrations of al-oh bands at 698 cm-1 and stretching modes at 780, 1056, and 3655 cm-1 for (si-o and al-mg-oh) bands, respectively. sem micrographs showed surfaces with varying platy polycrystalline particle sizes, while xrf results identified the clay as kaolinite with silicate and alumina > 30 and 16%, respectively. the flooding experiment revealed that the sds-mediated kb clay nps (8.33 mm sds) gave the highest total oil recovery of 66.25 % at 0.10 wt. %. optimizing oil recovery at 8.33 mm by varying concentrations of kbc2 at 0.05, 0.10, 0.15, 0.20, and 0.25 wt. % gave a remarkable oil recovery rate of 85.27% at 0.15 wt.%. thus, 0.15 wt. % kbc2 is recommended for application in oil recovery.
