Photodegradation of BTEX and odorous compounds by Fluidized Bed Gaseous Reactor with TiO₂/SiO₂ Photocatalysts

Abstract

Benzene, toluene, ethylbenzene, xylene (BTEX) and odorous compounds are the typical volatile organic compounds (VOCs) found in urban area and industrial sites. The photodegradation of BTEX in photocatalytic fluidized bed reactor with TiO₂/SiO₂ is investigated. The TiO₂ film is prepared by the sol-gel method and coated on the silica-gel powder. The UV lamp is installed in the center of the reactor and the BTEX is analyzed by GC/FID/MSD. The odorous compounds are analyzed by Multi-matrix Cryo-Concentration System integrated with GC.
