摘要： A method for recovering cobalt, ruthenium, and aluminum from spent Co—Ru/Al2O3 catalyst. First, Co—Ru/Al2O3 spent catalyst is subjected to hydrocarbon removal, reaction with hydrogen, and alkali fusion to obtain a slag. The slag is subjected to acid leaching, precipitation of cobalt with oxalic acid or ammonium oxalate, reduction of cobalt oxalate, and dissolution of cobalt metal with nitric acid to obtain Co(NO3)2.6 H2O. The effluent of acid leaching is subjected to reaction with ethanol, filtration to obtain a filtrate and residue, dissolution of the residue with concentrated hydrochloric acid, and vacuum distillation to obtain β-RuCl3.x H2O. Aluminum hydroxide is prepared from the filtrate through carbonation and calcination. The cobalt yield is ≧97%; the ruthenium yield is ≧95%, and the aluminum yield is ≧92%.
