Abstract
PURPOSE: To recover a noble metal from a used catalyst having the metal supported on a porous inorg. substance in a high recovering yield while preventing the carrier from being leached out by subjecting the catalyst to oxidation and reduction at a regulated temp. followed by extraction with an inorg. acid.
CONSTITUTION: When a noble metal such as a Pt group element is recovered from a used catalyst having the metal supported on a porous inorg. substance such as activated alumina, the catalyst is calcined at ≥1,000°C in an oxygen atmosphere to remove stuck org. matter by oxidation. In order to reduce the noble metal oxidized by the operation, the catalyst is reduced at ≥200°C in a hydrogen atmosphere, and then extraction is carried out with an inorg. acid such as aqua regia to efficiently recover the noble metal. By raising the calcining temp. to ≥1,000°C, the carrier such as alumina is prevented from being leached out during the extraction, and the recovering process is simplified, resulting in an enhanced recovering yield.
