Abstract
Provided is a process for the comprehensive recovery of metal cobalt ruthenium and aluminum from a waste catalyst Co Ru/AlOin a Fischer Tropsch synthesis. First a waste catalyst is subjected to hydrocarbon removal and reduction treatment to effectively separate a cobalt slag in an alkali fusion step and then the cobalt slag is subjected to the steps of acid leaching cobalt precipitation with oxalic acid or ammonium oxalate reduction of cobalt oxalate dissolution of metal cobalt with nitric acid etc. to obtain Co(?O)•6?O. A ruthenate which is dissolved by steps such as alkali fusion and leaching with deionized water is subjected to the steps of reduction with ethanol dissolution with concentrated hydrochloric acid distillation under reduced pressure etc. to obtain a ß RuCl•XHO product with a high purity. Aluminum hydroxide is prepared from a meta aluminate solution by CO carbonation by controlling the parameters such as reaction temperature flow rate of CO pH value at the end point of the reaction etc. and the aluminum hydroxide is calcined to obtain aluminum oxide with a product quality achieving the quality requirements of first class aluminum oxide in the Chinese national standard. The resulting product has a high yield wherein cobalt is = 97% ruthenium is = 95% and aluminum is = 92%.
