Pd/γ-Al₂O₃ can be used as a hydrodechlorination catalyst for both the water and the gas phase. A comparison of the catalytic hydrodechlorination of 1,1,2,2-tetrachloroethane (TeCA) in water and in the gas phase at various temperatures with Pd/γ-Al₂O₃ revealed Arrhenius parameters identical for the reaction in both phases: ln (A_Pd (l/(gmin))) = 22.8±0.9, E_A
