| titleOfInvention | A kind of method that fluidized bed process purifies platinum group metal from dead catalyst |
| abstract | The present invention discloses a kind of method that fluidized bed process purifies platinum group metal from dead catalyst, it is characterized by: first to spent auto catalysts crushing grinding to 150 mesh, roasting removes carbon, sulphur at 650 DEG C, restores by sodium borohydride aqueous solution, and HCl-NaCl-HClO is used when leaching 2 —Na 3 C 6 H 5 O 7 System leaches dead catalyst, and Cl is introduced into reactor when Leach reaction carries out 10 ~ 20min 2 , the fluidizing gas velocity of fluidized bed is 0.08m/s ~ 0.2m/s, to effectively improve platinum group metal leaching efficiency, and then improves the platinum group metal rate of recovery.It is 20min or so that it is most short, which to leach required total time, in platinum group metal by the present invention, handles the dead catalyst platinum rate of recovery >=96.5%, palladium recovery rate >=96.6%, the rhodium rate of recovery >=87.5% using the present invention. |
