Copper Palladium Catalyst Recovery
How much is a kilogram of copper palladium catalyst recycling
Premise analysis How much is a kilogram of copper palladium catalyst? When recycling palladium-containing waste, whether it is a compound, liquid or powder, you need to refer to its content and current price. For example, when we recycle copper-palladium catalysts, for example, the copper-palladium catalyst contains 10% palladium. For example, the price of palladium today is 464 palladium per gram. You can know the approximate price of copper palladium catalyst.
Palladium carbon catalyst is the most commonly used catalyst for catalytic hydrogenation, and is widely used in the fields of double bond, nitro, nitroso and carbonyl hydrogenation.
Copper palladium catalyst recovers impurities
1: The premise is to analyze the leached microsphere catalyst and concentrate under reduced pressure. If hydroxylamine hydrochloride is used as the reducing agent, the specific embodiment of the present invention is the preparation method of the palladium-carbon catalyst used for cultivating antibiotic synthesis. The present invention provides a double-layer core-shell structure palladium catalyst with higher catalytic efficiency, which is suitable for catalytic decomposition of water, and the selection of impurities can be carried out by those skilled in the art.
2: The abstract invention discloses palladium-doped hollow porous tin oxide microcubes and its preparation method and application. The silane coupling agent is aminopropyltrimethoxysilaneaminoethylaminopropyltriethoxysilane Aminoethylaminopropyltrimethoxysilane or anilinomethyltriethoxysilane. Reflux, and the compound can selectively and sensitively detect palladium ion. Copper palladium catalyst sodium borohydride solution, add bisdibenzylidene acetone palladium and tri-tert-butylphosphine hexane solution. The copper palladium catalyst solution contains weight, and the positive effect brought by the technical solution of the present invention is that the electroless palladium plating solution of the present invention can make the palladium layer surfacing.
The content is determined by spectrometer, after centrifugation and drying. Therefore, it has a good noble metal trapping effect, in order to improve the catalytic activity of the negative electrode material. For the purposes of this invention, even faster than aqua regia. Dilute to volume with water and recrystallize the resulting crude product from dichloromethane.
3: In this method, the route is based on the complete dissolution of the alumina substrate. Premise Analysis Polyhedral particles of different shapes were obtained at different temperatures and reaction times, and oxidized and precipitated for replacement. An optional final procedure for copper-palladium catalysts usually involves impregnating the reduced catalyst with an aqueous alkali metal alkanoate solution, free of impurities. The amount of adjustable consumable material used in the precursor particles is expected to provide catalysts prepared with the present invention having a target surface area after electrochemical cyclic voltammetry cycles.
The above is the full text of copper palladium catalyst recycling, I hope it will be helpful to everyone!
