Catalyst Thermal Oxidizer - CTO
CTO Catalytic Treatment
Organic pollutants in the exhaust gas are converted into harmless substances when the required oxidation temperature is reached. In conventional thermal oxidation, this temperature is typically very high, generally between 700 and 800°C.
Because substantial energy is required to heat the exhaust gas to such temperatures, the use of a catalyst can reduce the required reaction temperature and therefore reduce energy consumption. With newer-generation catalytic technologies, the reaction temperature can be reduced to below 200°C, providing significant potential for energy and operating cost savings.
SATTi utilizes single-atom catalyst technology that can reduce the operating temperature to below 200°C while achieving a VOC conversion efficiency of >99%, with no by-products as stated in the original performance data.
This technology provides a new energy-saving approach and represents a new generation of catalytic technology. The TOF value of the single-atom catalyst is approximately 2 to 3 times that of nanoparticle catalysts.

Next-Generation Advanced Single-Atom Catalyst
| Property | Conventional Catalyst | Core-Shell Catalyst | Single-Atom Catalyst |
|---|---|---|---|
| Catalyst Structure | — | — | — |
| Metal Utilization Efficiency (surface atoms / total atoms) | Low: <40% (10 nm particles as an example) | Low: 10–20% | High: 100% atomic utilization |
| Catalytic Activity | Light-off temperature: 250–300°C | Light-off temperature equal to or higher than conventional catalysts Influenced by shell porosity | Light-off temperature: <200°C Low-coordination atoms provide high activity Atoms are in extensive contact with the support Single-site bonding provides high selectivity |
| Sintering Resistance | Low Particles migrate and collide at high temperature Small particles can migrate toward larger particles with lower surface energy | Low Although protected by a shell layer, sintering similar to conventional catalysts can still occur | High Atoms are strongly anchored by metal-support interactions |
