Title of Process/ Know-how/ Product/Design/Equipment
Zeolite 13X Granules for Air Separation
Application/Uses/Problem being addressed
Salient Technical Features including Competing Features/ Impact
The nitrogen adsorption capacity of developed granules is comparable with commercially available adsorbents for oxygen separation from air.
TRL Level & Scale of Development:
Business scope & opportunity (in terms of scale, cost, market etc.):
Presently, the Indian requirement of air separation grade Zeolite 13X is mostly fulfilled by imported adsorbents. Therefore, the developed Zeolite 13X granule process has an excellent opportunity for indigenous adsorbent production.
Environmental Considerations:
The process generates alkaline effluent containing sodium hydroxide which can be treated using appropriate techniques to recycle/reuse DM or RO water.
Status of Licensing:
Not yet licensedStatus of Commercialization:
Not applicableMajor Raw Materials Needed
Silica source (sodium silicate or silica-containing waste), Alumina source (Sodium Aluminate, Aluminum Trihydrate, or alumina waste), sodium hydroxide, RO or Demineralized water and Clay binder
Major Plant Equipment and Machinery Required
Raw material storage tanks, solution preparation tanks, Jacketed Reactor with a stirrer, Pumps, Filter press, spray drier, packing unit, etc.
Techno-Economics
Technology using economic raw materials for the preparation of Zeolite-13X granules will make the process techno-economical feasible and competitive in the open market.
