摘要: Abstract In this research, selective catalytic oxidation was applied to remove high-concentration hydrogen sulfide in landfill gas. The removal efficiency of H2S the best with V/TiO2 catalyst produced by wet impregnation among. optimum vanadium content 10 %. addition, conversion elemental sulfur and generation SO2 could be controlled adjusting O2/H2S ratio. larger cell per square inch that affected performance honeycomb-type catalyst, greater according increase specific surface area. An analysis long-term gas including CH4 CO2 revealed more than 90 % removed. recovered thermal regeneration. Considering a can for durability regeneration, coated used actual process.
