RESIFA™ SOLESPHERE™ Fine Silica for Carbon Capture

These microspherical silicas are excellent CO2 absorbers when coupled with an amine treatment.

Product Inquiry Sample Request

 

With its unique pore structure, SOLESPHERE fine silica can allow a high absorption rate of CO2 and a high release rate at relatively low temperatures, reducing energy costs.

 

 

The combination of particle size and porosity provides a solid base for amine treatments to absorb CO2.

AGC also offers 3 different silica forms for this CO2 absorbing solution:

  • SOLESPHERE silica - for your original customized amine treatment
  • Silica Pellets - a combination of SOLESPHERE & micro fibrous silica
  • Aminated silica pellets

 

 

Absorption Performance

AGC-developed CO2 absorbent maintains relatively high absorption capacity even at low CO2 concentrations (eg, 1 vol%).

 

Desorption Performance

AGC's aminated silica can release high amount of absorbed CO2. At 80°C in ambient pressure, almost all portion could be desorbed within 1.5~2.0 hours.
