• Catalysts Business Line
  serves the life sciences, fine chemicals, industrial chemicals and polymers markets.
• Catalysts from the petro chemical industry, which are
  deactivated or cannot be used anymore, are one of the major processing activities
• The spent catalyst does not only contain the precious metals, but also other chemicals originating from
  the chemical process. These compounds can be solvents,
  reactants and any other chemical that was in contact with the catalyst.
• Spent Catalysts contain
  NiMo, CoMo, VNiMo, Mo, Ni, Co, Au, Ag, Cr, Cu, Fe, Pd, Pt, V, and Zn, or a
  combination thereof
• The leaching process provides pure metal oxides and concentrates where the melting process produces special or custom made metal
  alloys
• Recycle options include:  use of spent catalyst in fresh  catalyst manufacture;  use of ground spent catalyst material as a slag fluidizer additive in coal fired boilers; use of spent catalyst in bulk as a raw feed material for steel production; and
  materials recovery through chemical extraction
