    摘要: Disclosed is a method for preparing solid nitrosyl ruthenium nitrate by using a waste catalyst containing ruthenium. Steps of the method are: drying and calcining a waste catalyst containing ruthenium to acquire a black solid containing ruthenium, grinding the black solid containing ruthenium into powder, feeding hydrogen for reduction to form metal ruthenium, oxidizing metal ruthenium by using mixed gas of ozone and air to produce a ruthenium tetra oxide gas, collecting the gas, feeding the gas in a nitric acid solution, adding solid sodium nitrite to prepare a solution containing nitrosyl ruthenium nitrate, and finally using diethyl ether for extraction, and evaporating diethyl ether to acquire a nitrosyl ruthenium nitrate solid. The method can effectively reclaim noble metal ruthenium in various load-type waste catalysts containing ruthenium, so as to achieve effective recycling of ruthenium resources, and has simple operation steps and does not involve the introduction of ruthenium intermediates, which ensures a high product yield. The acquired solid nitrosyl ruthenium nitrate is free of halogen, has high purity, and is capable of being directly applied to the preparation of catalysts.

    摘要: Provided is a process for the comprehensive recovery of metal cobalt, ruthenium and aluminum from a waste catalyst Co-Ru/Al 2 O 3 in 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(N0 3 ) 2 ·6H 2 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 β-RuCl 3 ·xH 2 O product with a high purity. Aluminum hydroxide is prepared from a meta-aluminate solution by CO 2 carbonation, by controlling the parameters such as reaction temperature, flow rate of CO 2 , 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%.
