Honeycomb-structured CO2 adsorbent for direct air capture
Inorganic honeycomb-structured sorbent that selectively adsorbs atmospheric CO2 at 0-50°C and releases it at 150-500°C with no performance degradation over repeated cycles, enabling waste-heat-driven CO2 recovery.
Problem solved
Enables low-cost, low-energy CO2 recovery from ambient air and industrial exhaust using a honeycomb-structured sorbent that can be regenerated with waste heat (150-500°C), avoiding the degradation and volatility issues of amine-based absorbents.
Application contexts
- Direct air capture
- Industrial exhaust gas treatment
- Distributed small-scale CO2 capture
- Waste-heat driven CO2 recovery
Technical principle
Powder adsorbent performance is preserved while forming into a honeycomb structure, providing low pressure loss, high airflow processing, and high durability. The inorganic material composition resists thermal decomposition and degradation compared to amine-based alternatives.
Typical use cases
- Decentralized DAC units
- Small-scale industrial CO2 capture
- Waste-heat driven CO2 recovery from combustion exhaust
