Search of CatalystScavengers

Scavengers, or absorbents, separate and remove metals contained in chemical compounds.

Scavengers in N.E. CHEMCAT‘s CPs series are powder-type metal scavengers that collect metals from precious-metal containing organic solutions. These scavengers can efficiently absorb and collect metals, leading to reduction of residual elements in processes such as pharmaceutical product manufacturing, high-purification in semiconductor manufacturing, and recycling of metals, a scarce resource.

CPs-HP50

≪Characteristics≫

  • Efficiently absorbs and removes metals with different valence numbers
    CPs-HP50 efficiently absorbs and removes metals with different valence numbers contained in organic solutions.
  • Compatible with a wide range of metal species and organic solutions
    CPs-HP50 can be used for a wide range of metal species such as Pd, Pt, Ru, and Rh*.
    *We are also investigating application for Fe, Cu, Mn, Mo, and Sn.
    CPs-HP50 can be used for aqueous as well as organic solvents including toluene, dichloromethane, and ethanol.
  • Stability
    CPs-HP50 is stable across a wide range of pH from acid to alkaline.
    With its small temporal change, the product is also stable in the air and therefore is not easily affected by external air condition.
  • Can be used in columns
    The use in column was also taken into consideration in the design of catalyst’s shape and durability.

Scavengers and Sustainability

Loss of the precious metal resources due to scrapping is considered as an important global challenge with the heightened awareness toward SDGs and the sustainable society. Among them, precious metals for catalysts are used in large amounts. However, as they contain a large quantity of impurities, recycling of precious metals requires advanced technological capabilities and know-how to operate the process.

Since its foundation, N.E. CHEMCAT has been in the precious metal collection business. Under the corporate philosophy of “We contribute to achieving a sustainable and quality global environment and affluent society through chemistry,” we consider precious metal recovery as a critical challenge from the sustainability perspective. Thus, we are committed to developing technology for recycling precious metals, which are scarce resources.
