Structural Evolution of Magnesium-based Desulfurizers and Analysis of Their SO2 Adsorption Performance
Magnesium-based desulfurizers were prepared using a two-step process of hydrothermal synthesis and calcination. The effects of hydrothermal conditions(temperature 120-180 ℃,time 6-18 h) and calcination temperature(300-600 ℃) on the material structure and SO

adsorption performance were investigat

obtained by hydrothermal treatment at 150 ℃ for 12 h was converted into nano-MgO after calcination at 400 ℃. This nano-MgO exhibited a specific surface area of 94.7 m
2
/g,a mesoporous content of 78.6%,a negative shift of 0.4 eV in the Mg-O bond energy,a medium-strong base site density of 1.94 mmol/g,and an apparent activation energy of 36.2 kJ/mol. The optimized sample showed a breakthrough time of 198 min at 350 ℃ and a saturated sulfur capacity of 38.6%,representing improvements of 128% and 79%,respectively,compared to commercial MgO. The SO
2
adsorption process follows a pseudo-second-order kinetic model and is dominated by chemisorption. The mesoporous structure enhances the mass transfer efficiency,and the sulfur capacity retention rate is 82.3% after 10 cycles. This study lays the theoretical foundation for the directional design of high-efficiency magnesium-based desulfurization materials.
