Al-Ni alloy is a flammable metal material and a major hazard source. Nickel-based catalyst is a solid heterogeneous catalyst composed of fine grains of nickel-aluminum alloy with porous structure. It has the advantages of high mechanical strength, good catalytic activity, simple preparation and low price. It is widely used in hydrogenation, dehydrogenation, dehalogenation, desulfurization and other conversion reactions of petroleum, chemicals, pharmaceuticals, oils and fats, spices, hydrogen peroxide and synthetic fibers.
Al-Ni alloy catalyst is made of Al-Ni alloy powder after alkali treatment, also known as raney nickel catalyst, which has the functions of hydrogenation, deoxidation and methanation. Nickel-aluminum alloy powder is widely used in the market, mainly used in petrochemical, pharmaceutical, petroleum, spices, dyes, synthetic fibers and other industries.
