There are a number of ethylene removal technologies available.
- Catalysts. often based on platinum/aluminum, these operate at elevated temperature(>200) and catalytically oxidise ethylene to carbon dioxide and water.
- Use of photocatalytic oxidation of ethylene using titanium dioxide, which can occur at room teperature.
- Stoichiometric oxidising agent. mostly based on potassium permanganate, which again oxidises ethylene and is itself reduced.
