发明名称	Regeneration of supported noble metal hydro-dehalogenation catalyst without dioxin formation
摘要	Regeneration of deactivated supported noble metal catalysts (I) for hydro-dehalogenation comprises (a) treating (I) with H2 for 0.5-10, esp. 3-5 hrs. at the final hydro-dehalogenation temp.; (b) heating in the H2 stream and purging in H2 for 1-10 hrs. at 350-530, esp. 420-490 deg C; (c) rendering (I) inert with N2; and then (d) treating (I) in stages with an inert gas mixt. contg. O2 at 350-500, esp. 440-490 deg C.
