| titleOfInvention | Recovery method of platinum group metals from spent active carbon catalyst |
| abstract | The present invention relates to a method for recovering a platinum group metal from a noble metal-containing activated carbon spent catalyst used in petrochemical or various industries. More particularly, the present invention relates to a waste catalyst containing water and various organic substances, including H 2 O, NaOH, alcohols, and the like. The present invention relates to a method of recovering platinum group metals such as platinum and palladium by completely calcining volatile organic substances and the like remaining in a spent catalyst after washing and removing organic substances using an organic solvent.n n n As in the recovery method of the present invention, if the organic matter present in the waste catalyst is first removed before the waste catalyst is calcined, it is possible to reduce the occurrence of manure due to incomplete combustion during firing, Losses can also be reduced.n n n In addition, the platinum group metal mixture obtained after firing is reduced by using a reducing agent such as N 2 H 4 ยท 2H 2 O or a hydrogen mixed gas, and the platinum group metal is dissolved using various compounds to recover the platinum group metal. It can be obtained in high yield. |
