摘要：
The influence of the addition of different amounts of vanadium on the activity and resistance to poisoning of a 0.5% Pt/Al2O3 catalyst used in the hydrodechlorination of tetrachloroethylene was studied. Experiments carried out at 350 ○C were devoted to compare the effect of different vanadium loads on the deactivation of the catalyst. A catalyst with 0.12% V and reduced at 500 ○C presents the best performance. The performances of this catalyst and the non-doped Pt/Al2O3 were compared at 250 ○C in a longer experiment (85 h), resulting better the bimetallic catalyst.
