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

在这项研究中，采用选择性催化氧化去除垃圾填埋气中的高浓度硫化氢。其中，湿法浸渍法制得的V / TiO ₂催化剂对H ₂ S的去除效果最好。最佳钒含量为10％。另外，可以通过调节O ₂ / H ₂ S比来控制向元素硫的选择性转化和SO _2的产生。每平方英寸会影响蜂窝型催化剂性能的单元越大，根据比表面积的增加，H ₂ S的去除效率就越高。含CH ₄填埋气体的蜂窝型催化剂的长期性能分析CO ₂显示出90％以上的H ₂ S被去除。另外，可以通过热再生来恢复催化剂的性能。考虑到可以恢复催化剂的性能以提高耐久性和再生性，可以在实际工艺中使用V / TiO ₂涂覆的蜂窝型催化剂。
