Abstract

Novel catalysts comprising noble metals (Pt), supported on fiber-glass woven materials demonstrated efficient oxidation of different chlorinated hydrocarbons (chlorobenzene, dichloroethane, dichloropropane, butyl chloride) and industrial mixed chlorinated organic wastes into HCl, СО2 and Н2О at moderate temperatures without formation of highly toxic by-products (dioxins, phosgene, polychlorinated hydrocarbons, elemental chlorine). The highest oxidation activity and selectivity was observed for the platinum catalysts produced from fiber-glass supports with increased acidity and with additional introduction of promoting elements (such as Co, Mn and Cu). Long-term tests (more than 100 h) have shown no deactivation of the said catalysts. In combination with competitive catalyst price (due to the extra-low content of Pt – below 0.05% mass) it opens the way for development of highly efficient and feasible technology for utilization and detoxication of various chloro-organic wastes.
