Abstract
The invention relates to catalytic compositions for the hydrogenation of 1,1,2-trichloro-1,2,2-trifluoroethane to chlorotrifluoroethylene and trifluoroethylene comprising a porous oxygenated support impregnated with a metal of group VIII of the periodic table of the elements and one or more compounds chosen from the salts of an alkali or alkaline-earth metal. The invention also relates to a process for obtaining these catalytic compositions and a process of hydrogenation by means of these catalytic compositions.
