本研究针对石油炼化加氢催化剂中金属回收的问题,提出了一种高效的回收工艺。采用调节pH沉铝、煅烧制备氧化铝、镁盐除磷、钙盐沉钼和钡盐沉钼等步骤,实现了铝、钒、钼等贵金属的高效率和高纯度回收。实验结果显示,铝去除率高于95%,钼损失率低于5%,磷去除率超过99%,钒沉淀率超过94%。此工艺在确保贵金属有效回收的基础上,兼具成本效益,展示了良好的市场应用潜力。

This study proposes an efficient recovery process for metals in petroleum refining hydrogenation catalysts.The efficient and high-purity recovery of precious metals such as aluminum,vanadium,and molybdenum has been achieved through steps such as adjusting pH for aluminum precipitation,calcining to prepare aluminum oxide,magnesium salt for phosphorus removal,calcium salt for molybdenum precipitation,and barium salt for molybdenum precipitation.The experimental results show that the aluminum removal rate is higher than95%,the molybdenum loss rate is less than 5%,the phosphorus removal rate exceeds 99%,and the vanadium precipitation rate exceeds94%.This process not only ensures the effective recovery of precious metals,but also has cost-effectiveness,demonstrating good market application potential.
