<P>Magnesium oxides (MgOs) were synthesized by polyol-meditation thermolysis, hydrothermal, and aerogel methods and utilized to remove sulfur compounds from municipal gas. The capacity to remove methyl mercaptan (291 mu mol/mol) from methane was evaluated by using an adsorption breakthrough method at different temperatures. Then, to improve the sulfur removal capacity, a MgO-SiO2 composite was developed using the aerogel method and its breakthrough capacity was compared to those of the MgOs. The synthesized MgOs and MgO-SiO2 composite were characterized by XRD, BET, TGA, and HR-TEM. The MgO prepared by the aerogel method had the highest surface area and sorptioh capacity among the as-synthesized MgOs. Furthermore, the sulfur sorption capacity of the MgO-SiO2 composite prepared by the same aerogel method as MgO was three times higher than the aerogel MgO even though the sorption capacity of SiO2 was negligible.
