Zeolites, molecular sieves

NECA|zeo® und NECA|cms® – zeolites and molecular sieves for pressure swing adsorption in PSA plants

NECA|zeo® is the generic term used for different types of zeolites and molecular sieves for the pressure swing adsorption of technical and biogenic gases.

With NECA|cms®, we also provide you with carbon-based molecular sieves specially designed for the separation and production of nitrogen as well as for biogas upgrade (CO2 depletion).

Thanks to their availability in different geometric shapes and homogeneous pore structure in different sizes, this means you can use precisely the right product, depending on your own requirements, to enable the best possible result in your PSA plant – and we are more than happy to advise you here!

Zeolites and molecular sieves for the separation and dehumidification of technical gas streams

Synthetically produced microporous solids, alkaline, potassium-based or sodium-based. Can be used effectively in virtually any application thanks to their specific geometric shapes and homogeneous pore structure available in different sizes.

  • Separation and extraction of oxygen
  • Separation and extraction of nitrogen
  • Separation and extraction of methane
  • Separation and extraction of CO2
  • Removal of odorants
  • Removal of mercaptans
  • Drying of gases


Technical zeolites and molecular sieves, available in different geometric shapes and with different pore sizes

Carbon molecular sieves for the separation of technical gas streams

NECA|cms® are technical carbon molecular sieves for the excellent separation of gases in pressure swing adsorption (PSA).

Our carbon molecular sieves are characterized by a precisely defined micro-pore system, with long-lasting and reliable performance. Due to their high hardness, dust and abrasion are minimized during operation. Various quality classes open up a wide range of possible uses for the user.

In addition to delivery with NECA|cms®, NECATEC always offers you comprehensive technical advice and a professional exchange service.
