Hannae’s technology recycles 80% of the waste catalysts.
Tungsten, vanadium, and titanium that are recovered from waste catalysts will be used as valuable materials in various industries.
Tungsten means ‘heavy rock’ in Swedish with a specific gravity of 19.25g/cm³.
Tungsten boasts one of the highest melting points and 60% of the total tungsten production is used to produce high strength metal products using tungsten carbide.
It is used in a wide range of various industries, namely high strength steel production as source of alloy in the steel industry and extreme environment related fields, such as aeronautics, space, and defense industries
Vanadium was named after the Scandinavian goddess of beauty and fertility, ‘Vanadís’. The name was attributed to the wide range of colors found in vanadium compounds. Small quantities of vanadium are contained in various minerals and fossil fuels. In general, it can be generated from processes, such as steel refining, crude oil refining, and uranium mining.
In use, it is used as alloy sources when manufacturing special steel in the steel industry and acts as a major catalyst in the reduction of nitrogen oxide in DeNOx catalysts. Furthermore, vanadium is also used as catalysts in the production of sulfuric acid.
Titanium was named after the Greek god ‘Titan’, the god of metal. It boasts high levels of strength, ductility, and corrosion resistance.
Titanium’s strengthen is the most outstanding in terms of mass among metals.
Accordingly, it is used in various products, such as aviation components, tennis rackets, and automobile wheels.
