摘　　要：研究利用废催化剂经过高压酸溶处理后,得到硅渣和含铝等金属元素的滤液与氢氧化钠反应制备铝酸钠溶液,再经过种分法制备高纯度氢氧化铝。这种方法可以有效处理硅含量较高的废催化剂。并且部分化学物质可以循环使用,降低了生产成本,减少废弃物对环境的污染。Under high pressure conditions ,the waste catalyst was translated into the filtrate of aluminum and other metal elements with the acid treatment, which be used for preparation of sodium aluminate solution with sodium hydroxide. This solution can be produced to high purity aluminum hydroxide. This method can effectively treat spent catalyst with high silicon content. And some chemicals can be recycled to reduce production costs and waste pollution to the environment .
