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, СО 2 and Н 2О 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.
