[Dechlorination of p-dichlorobenzene by metallic catalytic reduction technology].
Pd/Fe bimetallic catalysts were synthesized by chemical deposition and used to dechlorination treatment of p-DCB. Batch experiments demonstrated that the Pd/Fe bimetallic particles can effectively dechlorinate p-DCB. Dechlorination efficiency accounted for more than 90% at Pd weight ratio (Pd to Fe) 0.02% and metal to solution ratio about 4g/74mL in 90min. Dechlorination ratios were affected by reaction temperature, initial pH, Pd ratio and the addition of Pd/Fe. Chlorobenzene represented stable partially dechlorinated intermediates in the generation of benzene.
