Adsorptive-catalytic removal of CH3OH, CH3SH, and CH3SSCH3 from air over the bifunctional system noble metals/HZSM-5

摘要：

Nowadays, improvements are needed to achieve the highest purification level of odorous volatile organic compounds. An attractive possibility is to combine adsorption and oxidation. The bifunctional system noble metals/HZSM-5 is tested in oxidative removal of individual or mixed CH3OH, CH3SH, and (CH3S)2 in order to find an adsorptive-oxidative window of operation. Rh/HZSM-5 and (Au+Rh)/HZSM-5 catalysts demonstrate high activity and stability (sulfur-resistance) at temperatures as low as 320oC. A less active mono-metallic Au/HZSM-5 also provides an effective and stable oxidative removal of VOC + S-VOC at 500oC. A nonisothermal, microwave-assisted catalytic process on Au0-containing samples seems to be attractive for a further study.
