Poison Resistant Catalysts
Poison resistant catalysts are designed to be particularly durable to typical catalyst poisons. Even in the presence of catalyst poisons, they can keep a good VOCs destruction efficiency and a relatively long catalyst life at low temperatures.
Poison resistant catalysts make possible the use of CatOx even in cases where catalysts typically cannot be applied.
