Abstract In this work, the solubility of methane and ethane were studied in aqueous dispersion of silver nanoparticles (1, 5, and 10 ppm) at temperatures of 1, 2.5, 10, and 11.5 °C for methane and 2.5, 5, 10, 15.5 °C for ethane and at initial pressures 1 to 5.5 and 0.35–2.15 MPa for methane and ethane, respectively. The nanoparticles were synthesized and characterized through UV–vis spectroscopy, dynamic light scattering (DLS), and transmission electron microscopy (TEM) image. The results demonstrated that silver nanoparticles increased the solubility of methane and ethane up to 13 and 16% compared with pure water, respectively. The solubility of methane and ethane were enhanced by increasing the nanoparticles mass loading. The effect of nanoparticles on ethane solubility was more significant than methane solubility.

纳米银对甲烷和乙烷在水中溶解度的影响

摘要 在这项工作中，研究了甲烷和乙烷在银纳米粒子（1、5 和 10 ppm）的水分散体中的溶解度，在 1、2.5、10 和 11.5 °C 的甲烷和 2.5、5、10、乙烷为 15.5 °C，甲烷和乙烷的初始压力分别为 1 至 5.5 兆帕和 0.35 至 2.15 兆帕。通过紫外可见光谱、动态光散射 (DLS) 和透射电子显微镜 (TEM) 图像合成并表征纳米颗粒。结果表明，与纯水相比，银纳米颗粒将甲烷和乙烷的溶解度分别提高了 13% 和 16%。甲烷和乙烷的溶解度通过增加纳米颗粒的质量负载而增强。纳米粒子对乙烷溶解度的影响比甲烷溶解度更显着。
