Selective Oxidation of Hydrogen Sulfide to Sulfur over Activated Carbon-Supported Metal Oxides

摘要：

The catalytic oxidation of hydrogen sulfide (H2S) to sulfur on activated carbon-supported metal oxide sorbents (M/AC) for hot gas desulfurization was studied in the temperature range of 150-250oC.Various M/AC sorbents loaded with 1％ (wt) metal oxide were separately prepare d by pore volume impregnation.Sorbents of partial oxidation of hydrogen sulfide can be placed in the following order with respect to activity: Mn/AC > Cu/AC > Ce/AC > Fe/AC > Co/AC > V/AC.The DTG and forms of sulfur analysis evidenced that the main product of the catalytic oxidation of hydrogen sulfide was elemental sulfur.The metal oxides loaded on the M/AC surface improve the efficiency and selectivity for desulfurization,catalyze the reaction between hydrogen sulfide and oxygen to form element sulfur.The activated carbon,as an adsorbent,can store the element sulfur in its pore passage
