Technology
The science and engineering behind Captisme's carbon capture, conversion, and storage platforms.
Core Technologies
Solid Sorbent Chemistry
Our proprietary amine-functionalized solid sorbents are the foundation of both ARB™ and Capsys™. Engineered for maximum CO₂ loading capacity, rapid kinetics, and long cycle life, these materials outperform conventional liquid amine systems in energy efficiency and operational flexibility.
- Amine-functionalized mesoporous silica support
- CO₂ loading capacity: 2.8 mmol/g (40% above industry average)
- Cycle stability: >10,000 adsorption-desorption cycles
- Tolerance to SOx, NOx, and humidity
- Operating temperature: 40–120°C (compatible with waste heat)
Catalytic Conversion
Carbex™ runs on Captisme's proprietary heterogeneous catalyst system — a modified copper-zinc-alumina formulation enhanced with rare earth promoters. This catalyst enables the direct hydrogenation of CO₂ to methanol and other products with exceptional selectivity and durability.
- Cu/ZnO/Al₂O₃ base with Ce and Zr promoters
- Per-pass CO₂ conversion: >30%
- Methanol selectivity: >98%
- Catalyst lifetime: 18,000+ operating hours
- In-situ regeneration capability
Temperature-Vacuum Swing Adsorption
Our TVSA process is the engine behind Capsys™ direct air capture. By combining mild temperature swings with vacuum desorption, we achieve energy-efficient CO₂ release from our sorbents — enabling the use of low-grade heat and renewable energy sources.
- Adsorption at ambient temperature (15–35°C)
- Desorption at 80–100°C under mild vacuum
- Energy consumption: <1,500 kWh/tCO₂
- Compatible with solar thermal and waste heat
- Continuous cyclic operation with automated valve sequencing
Accelerated Mineralization
Captisme's mineralization technology dramatically speeds up the natural process of mineral carbonation. Concentrated CO₂ reacts with finely ground reactive minerals — basalt, serpentine, and industrial waste streams — to form thermodynamically stable carbonate rock in hours rather than millennia.
- Reaction rates 10,000× faster than natural weathering
- Compatible with basalt, olivine, serpentine, and mine tailings
- CO₂ fixation efficiency: >90%
- Product: stable MgCO₃/CaCO₃ suitable for construction aggregates
- Full MRV (measurement, reporting, verification) integration
