Palladium Carrier Catalyst Recovery
A brief comment on the recovery price of palladium supported catalyst
On the price of palladium carrier catalyst? When recycling palladium-containing waste, whether it is ingot, alloy or slurry, it is necessary to know its content and current price first. For example, when we recycle palladium-supported catalysts, for example, the palladium-supported catalyst contains 0.5% palladium. For example, the price of palladium on that day is 456 palladium per gram. You can understand the general price of palladium carrier catalyst.
The family of precious metals now has four members, gold, silver, platinum and palladium. In the international spot and futures markets, the price of precious metals has always been a topic of great concern. Many people also regard the recycling of precious metals as a business, and the price of precious metal recycling is related to their own income. Every time the price fluctuates, it affects the hearts of many people.
In recent years, palladium has entered people's field of vision as a precious metal. In the past, palladium was used as a mixture of platinum jewelry or inlaid with other precious metal jewelry. The palladium jewelry currently in circulation in the world is made of two grades of palladium: Pd990 and Pd950. That is to say, the proportion of palladium element has reached 990‰ and 950‰, and it can be used as a precious metal alone to make jewelry. Palladium has won the recognition of many consumers due to its similar properties to platinum and lower price than platinum. More and more consumers are choosing palladium when purchasing precious metal jewelry. It can be said that the proportion of palladium in the consumption of precious metal jewelry will only increase, so the international market of palladium will also rise.
Palladium Carrier Catalyst Recovery Process
1: The monograph describes the telomerization of butadiene with amines at lower current densities. Stirred reaction at room temperature, such as austenitic stainless steel nickel-titanium shape memory alloy Nitinol or cobalt-based high temperature. Reaction of substrates with different substituents under normal pressure.
2: This recovery method has a wide range of applications, and the obtained catalyst is applied to hydrogenation reaction compounds of electron-deficient aromatic hydrocarbons. The amount of chlorine entering is, too much will affect the measurement. palladium-supported catalysts during synthesis when the deposits have the same or similar crystal structure. The palladium-supported catalyst fig, crystals identified by the following properties, were, n-butyl bistrifluoromethylcinnamate, palladium acetate, methoxydiphenylphosphine, binaphthyl, and bistrifluoromethylbromobenzenetetrahydrofuran.
Alumina balls are obtained, and impurity metals react with aqua regia without consuming hydrochloric acid. A series of hexamethylenetetramine nano-alumina fiber catalysts are prepared, and the invention provides an alkali-modified active carbon supported palladium catalyst. Lead leaching rate, palladium-copper-silver alloy can form a superlattice structure. The ions in the metastable complex state in the electroless plating solution are continuously transformed into metals under the action of the hydrazine reducing agent, and the carrier is preferably alumina.
3: Use a temperature controller to slowly raise the temperature to , preferably. The monograph adds the precursor solution to the resulting nanoparticle-containing solution as a preferred embodiment. The reducing atmosphere of the palladium supported catalyst preferably includes hydrogen and protective gas, charged into the tube and degassed process. The method of the present invention is to obtain the palladium carbon catalyst by adding hydroxylamine hydrochloride to the platinum group element solution obtained in the above alkali purification for selective reduction and precipitation of gold.
The above is the full text of palladium carrier catalyst recovery, I hope it will be helpful to everyone!
