英文摘要	destruction of polychlorinated aromatic compounds was carried out over spinel-type catalysts xy(2)o(4) (where x = mg, ca, cu, ni, zn, and y = al, fe). the catalysts were characterized by xrd, nitrogen adsorption desorption isotherms and ftir. the performance of these catalysts toward the decomposition of hexachlorobenzene (hcb) and octachlorodibenzo-p-dioxin (ocdd) was evaluated in a closed system. the spinel-type catalyst with mesoporous structure demonstrated high catalytic activity for the hydrodechlorination of polychlorinated aromatic compounds. among them, the copper aluminum spinel (cual(2)o(4)), specifically calcined at 600 degrees c, exhibited the best activity. more than 85% dechlorination efficiency of hcb and 99% decomposition of polychlorinated dibenzodioxin (pcdd) were achieved at 250 degrees c for 30 min over the above catalyst which was more effective than the corresponding metallic copper and copper oxide catalysts during the thermal degradation of polychlorinated aromatic compounds. the correlation of catalytic performance to structural characteristics is discussed based on the detailed characterization. the simple preparation procedure and reasonable cost of the spinel-type catalysts present a good potential for the thermal treatment of polychlorinated aromatic pollutants at lower temperatures.
