RCI DRI Molecular Sieves – Desiccants for Hydrogen Dehydration

Research Catalysts Inc.

  • RCI DRI Molecular Sieves for removal of water from Hydrogen and other gases
  • Can achieve deep Dehydration to < 10 ppmv of water
  • Available types include 3A, 4A, 5A, and 13X
  • Each type is available in particles sizes of 4x8 or 8x12 mesh
  • Uniform and precise pores sizes make molecular sieves ideal for certain purification processes.

RCI DRI Molecular Sieves – Desiccants for Hydrogen Dehydration

  • Molecular Sieves have a crystalline aluminosilicate structure with precise pore sizes between 3 and 9 angstroms depending on the type of the molecular sieve. This allows molecular sieves to selectively exclude adsorption of molecules with diameters larger than their pore size.
  • Molecular Sieves can effectively dry gases to low relative humidities and achieve dewpoints below -60°.
  • If used for water adsorption, Molecular Sieves can be regenerated by a drying procedure, allowing for many cycles of usage.

Key features

  • RCI DRI Molecular sieves can be used in combination with Research Catalyst’s Deoxo catalysts to purify Hydrogen in a Deoxo Dryer system.
  • Relatively high capacity for water uptake of around 20% by weight (temperature dependent).
  • Regenerable media allows for years of reuse before needing to be replaced

Application areas

  • Water Removal
  • Hydrogen Drying
  • Hydrogen Purification Units
  • Oxygen Drying
