Description
The present invention relates to the solid waste reutilization technology, particularly a kind of method that from the vehicle exhaust spent catalyst, reclaims metals such as platinum, palladium, rhodium.
Main active substances platinum in the cleaning catalyst for tail gases of automobiles, palladium, rhodium metal are immersed in the aluminum oxide coating layer on support of the catalyst surface, reclaim platinum, palladium, rhodium metal and have bigger economic benefit from used waste vapour car catalyzer.Prior art mostly adopts chloroazotic acid (or hydrochloric acid+oxygenant) dissolving for the research of reclaiming platinum, palladium, rhodium metal from waste vapour car catalyzer, adopts traditional chemical precipitation to separate the method for purifying then.Its yield of purification is lower, technology is tediously long and the method for platinum, palladium, the chemical precipitation of rhodium usefulness is separated.
The objective of the invention is to overcome the shortcoming of prior art, provide a flow process short, the novel method that metal recovery rate is high.
Technical scheme of the present invention is: put into by industrial sulphuric acid (H after will containing the spent catalyst fragmentation of metals such as platinum, palladium, rhodium earlier
2SO
4), dissolving is leached in the water solvent formed of technical hydrochloric acid (HCl), tap water, the dissolving later stage adds oxygenant (oxymuriate, hypochlorite), metals such as platinum, palladium, rhodium are immersed in the solution, through ion-exchange platinum, palladium are adsorbed onto on the resin again, rhodium is stayed in the exchange tail washings; Again with perchloric acid or sodium hydroxide solution drip washing resin, platinum, the synchronous desorb of palladium; Add solid ammonium chloride then in leacheate, make platinum be the ammonium chloroplatinate precipitation, the add-on of solid ammonium chloride is entirely suitable with the platinum precipitation, will contain palladium solution and add ammoniacal liquor complexing acidifying, and the ammoniacal liquor add-on is precipitated as suitable fully with palladium, and hydrazine hydrate reduction obtains palladium sponge; Add the copper powder displacement at last and reclaim rhodium in the exchange tail washings, the copper powder add-on is so that rhodium is precipitated as suitable fully.
The particle size after cracking of spent catalyst is the 1-3 millimeter in the aforesaid method, and the solvent that described dissolving step is used and the weight proportion of the spent catalyst after the fragmentation are: solvent: spent catalyst ratio=3.5-4.5: 1, and the initial acidity of solvent: HCl3-4mol/L, H
2SO
410-14mol/L; Dissolving initial reaction temperature 〉=100 ℃.The add-on of the oxygenant in dissolving later stage is the 10-20g/Kg spent catalyst.Described exchange resin is the resin of energy selective adsorption platinum, palladium complex anion.Describedly separate that to smoke eluent be 10-20% high chloro acid solution or aqueous sodium hydroxide solution.
The present invention compared with prior art has the advantage that technology is simple, metal recovery rate is high, the platinum rate of recovery＞96% wherein, and palladium recovery rate＞97%, the rhodium rate of recovery＞90%, platinum, palladium, rhodium product purity are all 〉=99.95%.
The present invention is described in further detail and verifies its effect below by embodiment.
