Abstract

Surface-modified mesoporous silica nanoparticle (MSN) with methyl groups was used to enhance the CH₄-water volumetric mass transfer coefficient (k_La) and the solubility of CH₄ in water. Two types of samples were tested: unmodified MSN and methyl-modified MSN. The mass transfer for each type of sample was measured every 20 s by gas chromatography. The results showed that the methyl-modified MSN, which have both hydrophobic and hydrophilic properties on the surface, exhibited higher CH₄-water volumetric mass transfer coefficient and solubility in water. The dissolved concentrations of CH₄ were enhanced by 10.7% and 27.8%, and the volumetric mass transfer coefficient were enhanced by 28.6% and 84.7%, respectively, by using unmodified MSN and methyl-modified MSN.
