Catalysts: NiAl Granules, Powder
01
Description
POLEMA produces metal powders and granules for non-coated catalysts used in various chemical processes. Powders and granules made of Ni50Al alloy and titanium-promoted NiAl alloy have high mechanical strength, stability, and selectivity in the hydrogenation of organic compounds after aluminum dealkalization.
02
specifications
NiAl alloys are used as starting materials in the production of nickel skeletal catalyst ("Raney nickel") for hydrogenation of compounds.
Ni-Al, Ni-Al-Ti alloys are made by melting of metal components and subsequent mechanical grinding of these material to achieve the required size.
