In this study, it was investigated on the deodorization system of a higher concentration hydrogen sulfide (H2S) with a contactless module including mesh screens and photocatalysts. In a conventional system, it was not able to obtain a higher deodorization efficiency of H2S due to photocatalyst's poisoning for a long time in the contact modules. To prevent poisoning on photocatalysts and to improve deodorization efficiency, it was synthesized the TiO2 photocatalyst with a higher specific surface area and doped dye film in the study. The photocatalysts were fixed on the mesh-matrix screen by a dip-coating. From the research, it was improved deodorization efficiency of H2S from under 50% to over 95% using the contactless modules with a TiO2-mesh screen from the research. |
