Sulfur removal from municipal gas using magnesium oxides and a magnesium oxide/silicon dioxide composite

Mesoporous MgO sorbent promoted with KNO3 for CO2 capture at intermediate temperatures

“…In this study, MgOÁKNO 3 composites were synthesized using an aerogel procedure applied for pure MgO synthesis in the previous work [31]. At room temperature, a mixture of toluene (100 mL) and magnesium methoxide (20 mL) was stirred in a glass reactor for 30 min.…”

“…And the crystallite size of the one-step calcination sample (11.0 nm) was much larger than that of the four-step calcination sample (7.9 nm) as shown in Table 1. The crystallite size of MgO can be significantly affected by synthesis methods [31]. In addition, it could be controlled by the calcination method [48].…”

Controlling the Physical Properties of Magnesium Oxide Using a Calcination Method in Aerogel Synthesis: Its Application to Enhanced Sorption of a Sulfur Compound

“…24 In the previous study, the performances of MgO compounds prepared by polyol-meditation thermolysis, hydrothermal, and aerogel methods were compared. 25 When the same calcination method was applied, the aerogel MgO had the highest surface area and sulfur sorption capacity among the as-synthesized MgO compounds. Also, a MgO/SiO 2 composite contributed to improving the sorption capacity following the same aerogel method.…”

Mesoporous magnesium oxide and its composites: Preparation, characterization, and removal of 2-chloroethyl ethyl sulfide

“…It has been reported that MgO with high surface area and pore volume can be obtained via an aerogel method using magnesium alkoxide and hypercritical drying [6]. Compared to polyol-meditation thermolysis and hydrothermal methods, aerogel MgO has shown outstanding textural properties and high sorption capacity of methylmercaptan in municipal gas [7].…”
