REJUVENATION OF LEAD-POISONED NOBLE METAL CATALYSTS
The acetic acid-ammonium acetate methods of catalyst rejuvenation by lead removal have been of considerable interest. The effectiveness of these methods was therefore investigated in the laboratory as a function of temperature, duration of treatment, type of agitation, and cation, using mainly catalyst samples poisoned by treatment with a lead acetate solution, with confirmation by vehicle-aged catalyst samples. The results have, in general, been encouraging. /GMRL/
