TECHNOLOGY OVERVIEW

In recent years, there has been an increasing demand for carbon dioxide (CO2) adsorbents due to climate change. These materials can be used for CO2 capture in both flue gas and directly from the air which can mitigate and reduce greenhouse gas (GHG) emissions. The current conventional CO2 adsorbents includes alkaline salts, aqueous amine solution and metal organic frameworks (MOF). However, these materials are expensive (MOF) and suffers from problems such as heat generation (alkaline salt) to energy intensive post-adsorption recovery (aqueous amine solution) which severely limits its wide scale adoption.

This technology offer is an amino-based resin adsorbent for low concentration and ambient temperature CO2 adsorption and desorption. This adsorbent is capable of adsorbing low concentrations of CO2 in air at room temperature and generates little heat when adsorbing CO2. It is also possible to capture CO2 from flue gas in the same manner as well. In addition, the regeneration (release of CO2) of the adsorbent can be performed at low temperature with significantly less energy consumption than existing materials.

TECHNOLOGY FEATURES & SPECIFICATIONS

This technology offer is an amino-based resin adsorbent for low concentration and room temperature capture of CO2. The technical features and specifications are as follows:

  • Porous amino-based resin
  • Easy to handle granules
  • High affinity CO2 chemisorption
  • Low concentration and temperature CO2 adsorption (as low as 400 ppm and at room temperature)
  • Desorption is possible at lower temperatures than existing materials (30 oC or higher)
  • Environmentally friendly (non-toxic, non-volatile)
  • Flexible implementation design (filter parts, filing columns etc.)

POTENTIAL APPLICATIONS

The use of this technology is for industries who are interested in CO2 capture and/or utilisation. The potential applications are:

- Scenarios for COCapture

  • Air conditioners (passive CO2 capture and indoor CO2 concentration control)
  • Manufacturing and other CO2 emitting industries (removal of CO2 from pre-combustion or flue gas)

- Scenarios for COUtilisation

  • Beauty applications (promotion of blood circulation by use of CO2)
  • Agriculture application (promotion of growth by use of CO2

Unique Value Proposition

  • Low concentration and room temperature CO2 capture
  • Desorption is possible at lower temperatures than existing materials (30 oC or higher)
  • Environmentally friendly adsorbent (non-toxic, non-volatile)
  • Flexible use case (direct air capture, flue gas capture)

This technology owner is keen to out-license this patented technology, or to do R&D collaboration utilising the adsorbent material with partners who are interested in CO2 capture and/or utilisation.
