Abstract

A range of platinum (Pt) exchanged zeolites were tested for the catalytic destruction of volatile organic compounds (VOC's) in air. The range of zeolites included ZSM-5 and β-zeolite in their acidic forms and the results are compared with conventional Pt/Al₂O₃, Pt/TiO₂ and Pt/SiO₂ catalysts. Catalysts typically contained 0.5-6.5wt% platinum and dispersions, as measured by hydrogen chemisorption, were in the range 39-65%. Toluene and ethylbenzene, prime indoor sources of VOC's, originating from paints, adhesives and combustion products were fed to the reactor in the concentration range 200-5000ppm with excess oxygen. Typically in our reaction conditions, 100% conversion of toluene or ethylbenzene could be achieved over Pt/β-zeolite and Pt/ZSM-5 below 175°C.
