Regeneration of spent Pd-active carbon catalysts by oxidation of deposited organic impurities with H2O2/O-3 sytem
Spent Pd(10%)-activated C catalyst was regenerated by treatment with H2O2 and O-3 and used for hydrogenation of PhCH=CHCOOH to PhCH2CH2COOH. The regenerated catalyst showed the same activity as the fresh (com.) one and the catalyst regenerated by supercrit. fluid extn.
