Abstract Scope |
Catalysts have been obtained using functionally active batches based on intermetallic compounds of the nickel-aluminum system with the Rane structure. A comprehensive study of the phase composition of the Ni-Al catalysts and the processes of their structure formation has been carried out. The effect of the phase composition of the Ni2Al3 and NiAl3 aluminides has been studied. The homogeneity region of the NiAl3 compound is very narrow, and the range of the Ni2Al3 compound is within 4 at.% nickel. Cast and leached Ni2Al3 and NiAl3 alloys have been studied. Microstructures of Raney nickel have been obtained and various characteristics of the catalysts have been studied. The activity of the obtained catalysts is inversely proportional to the concentration of nickel in the Ni-Al alloy. The leaching product of NiAl3, depending on the studied reaction, is 3-15 times more active than the Ni2Al3 catalyst. |
