Patent and Technology

What is NCCO?

Nano-Confined Catalytic Oxidation (NCCO) is a revolutionary technology. Compared to other air purification technologies, instead of “adsorb and release”, NCCO can achieve “adsorb and decompose”. This stops any secondary pollution to the environment which can happen with more traditional adsorptive technologies.

Most air purifying systems in the market target short-term benefits with disregard of sustainability. Activated carbon filters have a short service life (months) with the discarded filters and process of replacing such filters created pollutive industrial waste, putting pressure on the environment. NCCO truly resolves these problems, and this technology achieves impressive adsorptive, decomposition and cleansing action within the air purifying system. It’s a safe, sustainable and eco-friendly option.

NANO
Nano is a unit of measure for extremely small objects such as atoms and molecules. 1 nanometre is 1/1,000,000th of the diameter of human hair.

CONFINED
The shape-selective properties of our catalytic material allow their usage in molecular adsorption. A granule of catalytic material with a diameter of 0.4 cm has around 400 feet of adsorption tunnel. This catalytic material is able to absorb certain molecules whilst excluding others. This results in efficient removal of pollutants such as VOCs from the environment.

CATALYTIC
There are transition metals (Zeolites) impregnated within the porous structure of our catalytic material. These transition metals can act as catalysts to enhance the reaction between the gaseous contaminants and oxidants.

Theory of NCCO

NCCO – Nano Confined Catalytic Oxidation is able to convert VOCs (Volatile Organic Compounds) and Formaldehyde to harmless CO2 and H20 molecules. This technique involves the use of ‘contained’ ozone in combination with zeolites (crystalline solids with uniformly-sized, nano-scale pores) and other related porous materials. In contrast to ozone generators, which directly release the toxic gas into the environment and are known to be ineffective, NCCO greatly enhances the oxidation of contaminants while avoiding high emission of ozone and harmful reaction intermediates. The zeolites consist of a negatively-charged aluminosilicate framework with loosely bound cations that maintain the charge balance. A number of natural and synthetic zeolites with varying chemical compositions have been exploited for different commercial applications. Zeolite filters can be used in air purification for the adsorption of gaseous pollutants Interestingly, zeolites also have the ability to catalyze diverse reactions inside the nanosized pores . NCCO is based on a catalytic ozonisation mechanism where ozone (O3) provided by an upstream ozone generator is decomposed into molecular oxygen (O2) and active atomic oxygen (O*) at acidic sites of the adsorbent. Gaseous pollutants e.g. VOCs that are adsorbed in the same pore as O* undergo catalytic oxidation within the confined nano-cavity. Previous studies show that reaction intermediates remain in the adsorbent, while the smaller final products (such as carbon dioxide and water) are generally released to regenerate the catalyst. Based on the catalytic process, the life of the NCCO filter has an extremely long functioning and performance life.

Advantages of NCCO

  • Super powerful decomposition of medically harmful gaseous pollutants such as formaldehyde, xylene, benzene, acetone and phenol
  • Does not release secondary pollutants compared to traditional adsorbent materials such as activated carbon
  • NCCO reactants are recyclable and self-sustaining thus can be reused repeatedly, providing significant savings in labour and running costs
  • Uses mineral material as reactant and so preserves the external environment

Benefits of NCCO

  • Disinfects and Deodorises – Improves hygiene in critical areas
  • Reduces the number of air changes – Provides running cost benefits
  • Removes TVOCs – Reduces effects of medically harmful fume pollutants
  • Protects health of employees – Provides better working environment and increases in productivity
  • Kills bacteria and viruses e.g.H3N2 – Provides significant protection to individuals
  • Maintains good air quality – Provides a better living atmosphere and environment
  • Collects allergens – Using HEPA Filter (HEPA 13 – Medical Grade), reduces allergic reactions
  • Prevents inhalation of suspended particulates e.g.PM2.5 protection, improving Indoor Air Quality (IAQ) to EXCELLENT class
  • Removes smoke and harmful fumes –Providing personal and commercial benefits
