中文摘要 | 釩為最輕之高溫耐火稀有金屬,在鋼鐵中添加釩可增其強度、硬度,成為喜合金以及合金鋼、工具鋼、構造鋼等鋼品之原料。釩的化學品廣用於觸媒、色料、硫化氫吸附材料等工業,已成為吾人今日工業不可或缺之原料。然而自然界並無富集之釩礦床,其生產大多為其他金屬如(鈾、鐵)煉製之副產品,或由廢棄物中回收。 臺灣由於此類天然資源有限,因此如何將其從廢棄物中回收,便成為今日吾人努力的目標,本文基於此,首先說明釩之回收原理,其次就國內有之含釩廢棄物以燃料油灰渣、廢觸媒及高速鋼廢料為例,簡為介紹其發生情形,處理現況及回收流程。 |
英文摘要 | Vanadium, the ligthest refractory metal, could improve strength and hardness when added to steel, and is one of the raw materials of superalloys, tool steels as well as structural steels. The chemical compounds of vanadium are widely applied to catalysts, pigments and H2S adsorbent. However, owing to rareness of vanadium ore deposits in nature, the source of vanadium is largely obtained from by-products of other metal ores (U, Fe) or by recovering from wastes. In Taiwan, the awareness of scarcity of vanadium resources has become our crucial aim as how to recover vanadium from wastes. In this regard, this paper begins with the principle of vanadium recovery and then illustrates the occurrence, treatment, and recovery process of vanadium-bearing wastes such as fuel oil ashes, waste hydrodesulphurization catalysts, and waste high-speed steels. |
