Features & Benefits

- Properties
In the form of dark colored, amorphous granules, Moleculite® combines high catalytic activity with good abrasion resistance. Properties include:
- Large surface area, giving high oxidation efficiency
- Optimized copper oxide/manganese dioxide ratio
- Very low dust content
- In VOC applications operating temperature should be in excess of 20°C above the boiling point of the least volatile component
- How it works?
Moleculite® is an oxidation catalyst that acts as a substrate to combine an absorbed gaseous material with oxygen in the surrounding gas stream to produce oxidized products.
Moleculite®+ target material + [O2] gMoleculite® + oxidized target material
Providing the process is carried out at sufficiently high temperature the products are often only carbon dioxide and water.
The Moleculite® copper/manganese couple is able to both receive and donate oxygen to gas molecules at its surface and hence acts as a catalyst to oxidize materials whilst operating at temperatures much lower than would normally be the case.
Examples include
- Carbon monoxide to carbon dioxide and water
- Ethylene oxide to carbon dioxide and water
- Hydrogen to water
- Ethane to carbon dioxide and water
- Ozone to oxygen
- Volatile hydrocarbons to carbon dioxide and water (or other oxidized products depending on the temperature of operation)
Moleculite® can also oxidize many materials without the presence of oxygen in the gas stream but in doing so it is consumed and cannot act catalytically. This can be useful for example to remove small amounts of minor contaminants in a closed system.
