GONZALEZ, Carlos Andrés; BUSTAMANTE, Felipe  e  MONTES DE CORREA, Consuelo. Catalytic Hydrodechlorination of Dichloromethane, Chloroform and Tetrachloroethylene . Rev.fac.ing.univ. Antioquia [online]. 2006, n.38, pp.73-87. ISSN 0120-6230.

Kinetic parameters (reaction rate constants, reaction order and activation energies) were determined for dichloromethane hydrodechlorination in the presence of chloroform and tetrachloroethylene traces (loading between 0.3-0.8%) over Pd catalysts between 100-200 ºC. Two Pd supports were used: a commercial alumina and a titania xerogel. The activity increased with palladium loading. The presence of chloroform and tetrachloroethylene inhibited dichloromethane hydrodechlorination. Catalysts were characterized by X-ray diffraction, elemental analysis, nitrogen adsorption (BET), TGA, chemisorption, TPR.

Palavras-chave : dichloromethane; chloroform; tetrachloroethylene; alumina; titanium; sol-gel; kinetic; palladium.
