Do you know a method to recover nickel and aluminum from spent Raney nickel catalyst? The editor of Low price Maximum Nickel Resistance Catalyst will give you a brief look.
A method for recovering nickel and aluminum from spent Raney nickel catalyst, comprising an acid leaching step and alum precipitation step, is characterized in that: the alum precipitation step is that the spent Raney nickel catalyst is acid leached, and sulfuric acid is added to the leaching solution Ammonium and sodium sulfate, from which ammonium alum crystals are precipitated and a nickel sulfate solution is obtained. The process of the present invention is short, high in efficiency, low in consumption of auxiliary materials, and low in production cost; cobalt, nickel, and copper can be removed through the leaching step and the alum precipitation step, etc. It can be enriched in the analytical solution and recycled, the added value of the product is high, the recovery rate of nickel and aluminum is high, and the economic benefits are obvious; no waste residue or exhaust gas is generated during the process, and the discharge of waste water is reduced, which is environmentally friendly and avoids pollution and resource waste.
In summary, the editor of Low price Maximum Nickel Resistance Catalyst tells: about the method of recovering nickel and aluminum from spent Raney nickel catalyst.
