Sour Gas Adsorption on Silica Gels.

ABSTRACT: One of the essential factors for water adsorption on silica gels is the concentration of silanol groups on the silica surface. However, no systematic investigation on the adsorption of sour gas components, methane (CH₄), carbon dioxide (CO₂), and hydrogen sulfide (H₂S) on silica gels with different textural properties and surface silanol concentrations, has been conducted. Three silica gels of 22, 30, and 60 Å pore sizes, with silanol concentrations of α_total = 2.516, 2.340, and 2.152 OH nm^-2, respectively, were studied in this work. The adsorption data for CH₄, CO₂, H₂S, and H₂O at T = 0, 25, and 50 °C on the 22 and 30 Å pore size silica gels were presented, and a comparison of the da
