將廢觸媒粉末經鹼焙燒及熱水浸漬處理後,鉬之浸出率為 98%,釩之浸出率為 99%,砷之浸出率為 95%。
利用浸漬液中不同金屬離子對強鹼型陰離子交換樹脂的親和力大小順序可將Mo吸附與大部分V、 P、 As 、Si 、Al分離。以銨鹽脫附劑可解析富集Mo。在離子交換串柱操作條件下Mo之回收率接近100%。含Mo解析液經加入鎂鹽除As後,Mo之損失率僅0.15%,而除As率達100%。除As後解析液中過量之Mg以陽離子樹脂去除,除Mg率達100%,Mo無損失。純化後解析液經蒸發結晶,可產製七鉬酸銨產品,純度為Mo=98wt%、V=0.53wt%、As=0wt%,達到除As的目的。整體操作Mo之回收率為97%。
交換尾液利用不同金屬離子對強鹼型陰離子交換樹脂的親和力大小順序可將V可與大部分P、 As 、Si 、Al分離。以銨鹽脫附劑可解析富集V,在離子交換串柱操作條件下V之回收率接近100%。解析液靜置後,釩以偏釩酸銨形態析出,沉澱率=97%。產品純度Mo=0 wt %、V=99.5wt% 、As=0.28wt%,整體操作V之回收率為96%。
This study demonstrates the combination of the two unit processes to recover molybdenum and vanadium from involving high arsenic spent SCR catalysts. Those two unit processes are NaOH roasting-hot water leaching and ion exchange. The leaching rate of molybdenum, vanadium, and arsenic is 98%, 99% and 95%, respectively.
Through the affinity of the different metal ions in the impregnated solution by the strong base type anion exchange resin, we can resolve Mo. Then, desorb Mo with ammonium salt, the recovery of Mo is close to 100% under consecutive column. Mo loss only 0.15% after adding magnesium salt at Mo enrichment solution, and As can be removed 100%. Excessive Mg in the desorption solution is removed by cationic resin. The removal rate is 100%, and Mo isn’t loss. After purification, the desorption solution is crystallized by evaporation to produce (NH4)6Mo7O24. The product purity of Mo = 98 wt%, V = 0.53 wt% and As = 0 wt%. The overall recovery of Mo can reach 97%.
Through the affinity of the different metal ions in the impregnated solution by the strong base type anion exchange resin, we can resolve V from ion exchange solution. Then, desorb V with ammonium salt, the recovery of V is close to 100% under consecutive column. After static for a day, the desorption solution is crystallized to produce NH4VO3. The product purity of Mo = 0 wt%, V = 99.5 wt% and As = 0.28 wt%. The overall recovery of Mo can reach 96%.
