  • Patent number: 6342128
    Abstract: A new method for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The method is based on optimizing photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants. The technique is applicable to photo-thermocatalytic reactor design and scale-up. At low irradiance levels, the method is based on the implementation of low pressure drop biopolymeric and synthetic polymeric support for titanium dioxide and other band-gap media. At high irradiance levels, the method utilizes multifunctional metal oxide aerogels and other media within a novel rotating fluidized particle bed reactor.

  • Publication number: 20010050218
    Abstract: A new method for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The method is based on optimizing photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants. The technique is applicable to both low and high-flux photoreactor design and scale-up. The low-flux method is based on the implementation of natural biopolymeric and other low-pressure drop media support for titanium dioxide and other band-gap photocatalysts. The high-flux method is based on the implementation of multifunctional metal oxide aerogels and other media in conjunction with a novel rotating fluidized particle bed reactor.

  • Patent number: 5935538
    Abstract: A process is provided for conditioning fly-ash present in flue gas which also contains sulfur dioxide and steam by subjecting the fly-ash containing flue gas to ultraviolet radiation so as to convert steam present in the flue gas into hydroxyl radicals which oxidizes about 5 to 10 percent of the sulfur dioxide in the flue gas into sulfur trioxide. This photo-produced sulfur trioxide conditions the fly-ash and renders it more easily separated in the electrostatic precipitator.

  • Patent number: 5842110
    Abstract: A process for the in-situ transformation of chemical species present in the flue gas to form sulfur trioxide, wherein the fly-ash particles are conditioned by altering their surface electrical properties. More specifically, the subject invention is concerned with fly ash conditioning using plural lamps located at specific positions in a specific arrangements most advantageous to the chemical conversion that would take place. The novel invention conditions flue gas emissions by treating the flue gas with SO.sub.3, where the SO.sub.3 is generated in the flue gas by photocatalytic conversion of SO.sub.2 using selectively spaced and arranged ultra violet light emitting lamps and related automated components.

  • Patent number: 5744407
    Abstract: Methods of destroying toxic volatile air-borne toxins are disclosed. In a preferred embodiment, a piece of formaldehyde laden substrate(wood) such as paneling and furniture is treated with TiO.sub.2 solution to form a thin and translucent veneer on the surface. This layer acts like a membrane preventing outward transport of formaldehyde and other harmful compounds produced by weatherization and natural degradation of the substrate. In a prefered embodiment the photocatalytic destruction of formaldehyde is achieved. Other toxins destroyed include terpenes and other types of toxic volatile organic compounds(VOCs). While the prefered embodiment is applied to wood based supports such as paneling and furniture, the invention has applicability for other surfaces such as caskets and roof shingles. For example, the TiO.sub.

  • Patent number: 5296110
    Abstract: A process and apparatus for separating and concentrating breathing-grade oxygen, that is therapeutically equivalent to 100% pure oxygen, from ambient air is provided. The oxygen concentrating process employed in the method of the invention is implemented in a housing having a main chamber. A solid anion conducting membrane is situated in the main chamber so as to divide the chamber into separate first and second reaction chambers. Electrocatalytically active cathodic and anodic electrodes are situated on the respective opposed surfaces of the membrane. A direct current source is coupled between the cathodic and anodic electrodes such that when ambient air is provided to the cathodic electrode, therapeutically pure and moist oxygen is produced at the anodic electrode by electrolytic action of hydroxyl ions passing through the solid membrane.
