  • Patent number: 6773683
    Abstract: A photocatalytic reactor system consisting of a photonic energy source to remove undesirable contaminants from an effluent stream. The device includes a photonic energy source, a beam delivery system, and a reaction chamber into which the photonic energy is transmitted. The contaminated effluent flows through the reaction chamber where the photonic energy reacts with it to reduce contaminant emissions.
    Type: Grant
