Abstract

In recent years the implementation of stricter legislation limiting the permitted emission levels of aerial volatile organic compounds effluent has imposed increased costs on many industries. The challenge for industry has been to effectively control these emissions with minimum economic burden. One of the main effluent treatment technologies which has been employed for VOC abatement is oxidative catalytic destruction. In this study uranium oxide based catalysts have been investigated for the oxidative destruction of VOCs to carbon oxides and water. The catalysts have been tested for the destruction of a range of organic compounds at space velocities up to 70,000 h-1. The uranium based catalysts include both supported, unsupported and transition metal doped systems. Reactivity studies have shown that destruction efficiencies greater than 99 can be achieved over the appropriate uranium based catalyst in the temperature range of 150-450°C. The organic compounds investigated include benzene, butylacetate, cyclohexanone, butane and chlorobenzene. In the case of non-halogenated compounds the reaction products are carbon oxides and water, whilst the reaction of chlorobenzene also produces HCl. In the case of the destruction of chlorobenzene, no deactivation of the uranium based catalyst was observed. The observed reactivity and lifetime of the uranium based catalyst systems show there is good potential for the application of these materials in commercial VOC abatement systems.
