Nickel subsulfide catalyst

Uses/Sources. Corrosion-resistant alloys, electroplating, production of catalysts, nickel-cadmium batteries nickel subsulfide (NisS2) is encountered in the smelting and refining of certain nickel ores and may be formed in petroleum refining from the use of nickel catalysts. 

Nickel and nickel compounds are widely used in plated coatings, nickel-cadmium batteries, certain pigments, ceramic glazes, and as industrial and laboratory catalysts. Nickel subsulfide is used in refining certain ores and in smelting operations. Nickel is commonly used in alloys such as stainless steel, alloy steel, and nonferrous metal mixtures. Coins, costume jewelry, plumbing equipment, and electrodes are often made from nickel-containing alloys. 

Carpenter-Evans A catalytic process for removing organic sulfur compounds from synthesis gas by hydrogenation to hydrogen sulfide, which is absorbed by iron oxide. The hydrogenation catalyst is nickel subsulfide, Ni3S2. Invented by E.V. Evans and C.C. Carpenter in England around 1913 and operated in three commercial plants.
