Abstract

A microwave/UV/ozone/TiO ₂ photocatalyst hybrid process system, which is a combination of various propylene gas treatment techniques, is evaluated for use as an advanced, efficient technology for air pollution treatment. TiO ₂ photocatalyst balls were prepared using low-pressure metal-organic chemical vapor deposition. The microwave/UV/TiO ₂ photocatalyst hybrid process exhibited the higher degradation efficiency than the microwave/UV/alumina ball hybrid system. The degradation efficiency increased almost linearly with increasing ozone dose. The lower the propylene inlet concentration was the higher degradation efficiency. The double bond of propylene is broken by ozone and OH, resulting in production of CH ₄ and C ₂H ₆. These two intermediate products are mineralized into CO ₂, H ₂O, and CO. C ₂H ₄ and C ₃H ₈ may be produced from CH ₄, whereas C ₂H ₆ and C ₃H ₆ are produced by microwave irradiation.
