摘要
石化工业产生大量的以氧化铝为载体而失效的催化剂,本文采用钠化焙烧-浸出工艺研究了铝基废料中铝、钒和钼的浸出率,并对浸出渣进行二次浸出,研究镍钴浸出的可行性。试验结果表明,在最优条件下,铝、钒和钼的浸出率分别达97%、99.2%、99.8%。镍钴渣的富集物通过硫酸浸出可使镍和钴完全浸出。
The petrochemical industry produced a large number of catalysts that fail based on alumina,the leaching rates of aluminum,vanadium and molybdenum were studied by sodium calcination and leaching process,and the feasibility of nickel and cobalt leaching was studied by secondary leaching of leaching slag in this paper.Results show that the leaching rates of aluminum,vanadium and molybdenum were 97%,99.2%and 99.8%under optimal conditions respectively.Nickel and cobalt can be completely leached by sulfuric acid leaching.
