Utilization of Spent Catalyst (Solid Waste) from the Nitrogeneous Chemical Plant
Nitrogeneous fertilizer industry generated so many spent catalysts during the manufacturing of fertilizer’s. In production of ammonia and other products, different types of catalysts are used. After periodically use of the catalyst due to the poisoning effect of foreign material and impurities, whic...

| description | Nitrogeneous fertilizer industry generated so many spent catalysts during the manufacturing of fertilizer’s. In production of ammonia and other products, different types of catalysts are used. After periodically use of the catalyst due to the poisoning effect of foreign material and impurities, which deposit on the surface of the catalyst, they will become inactive. In such cases fresh catalysts have to be substituted and the spent catalyst will be discarded as waste material. Spent catalyst waste reduction at source can be achieved by using improved more active and more stable catalysts, regeneration and reuse of deactivated catalysts in many cycles, before the final disposal. The spent catalyst can be recycled by using them as raw materials for recovery of valuable metals and other products |
