Abstract (en)
[origin: EP0887087A2] In a batch reactor (1), complete with heat exchanger (2) and agitator (3), the dielectric oil (4) contaminated by polychlorobiphenyls is placed in contact with gaseous hydrogen (5) and caused to react therewith at temperatures between 250 and 400 DEG C and pressures between 5 and 50 bar in the presence of a hydrogenation catalyst (6). The decontaminated oil (7) is separated by means of a filter (8) from the recovered catalyst (9). <IMAGE>
