| Abstract: | Spent reforming catalysts are important raw materials for precious metal recovery plants. The basic processes of dissolving the carriers in spent reforming catalysts by sulfuric acid , hydrochloric acid, mixed acid and alkali and the pyrometallurgy method were compared. The routes of platinum recovery and aluminum comprehensive utilizationwere studied, and their advantages and disadvantageswere analyzed. Combined with the requirements of China''s environmental protection policies, it was proposed that the pressurized alkali dissolution carrier method was the best option at present. |
