ARDILA ARIAS, Alba Nelly  and  MONTES DE CORREA, Consuelo. A review of liquid-phase catalytic hydrodechlorination. Ing. Investig. [online]. 2007, vol.27, n.3, pp.52-64. ISSN 0120-5609.

This survey was aimed at introducing the effect of light organochlorinated compound emissions on the environment, particularly on water, air, soil, biota and human beings. The characteristics and advantages of liquid phase catalytic hydrodechlorination as a technology for degrading these chlorinated compounds is also outlined and the main catalysts used in the hydrodechlorination process are described. Special emphasis is placed on palladium catalysts, their activity, the nature of active species and deactivation. The effect of several parameters is introduced, such as HCl, solvent, base addition and type of reducing agent used. The main results of kinetic studies, reactors used and the most important survey conclusions are presented.

Keywords : light organochlorinated compound; liquid phase catalytic hydrodechlorinarion; palladium catalyst; HCl produced; reducing agent; base; solvent; kinetic study.
