Description:

Aqueous ion exchange in zeolites is currently hindered by the acidic byproducts that deteriorate the zeolite structure. This invention improves the ion exchange efficiency in zeolites by utilizing polymer solutions that do not damage the zeolite network. The result is an efficient zeolite that is ideal for ion exchange, catalysis, and gas exchange.

Applications:

  • Industries that use ion exchange, i.e., nuclear power, petroleum processing, etc
  • Lithium-ion batteries
  • Gas exchange

Advantages:

  • Increased ion exchange efficiency than zeolites with aqueous solutions
  • Ion exchange efficiency further increased by the use of zeolites with lower Si/Al ratio
  • Operation at intermediate temperatures, unlike molten salts
