  • Reactor for photooxidations in an aqueous environment
    Patent number: 5275741
    Abstract: The object of the present invention is a method for the photocatalytic treatment of aqueous mixtures of polluting substances. Such a method consists in submitting such mixtures to irradiation in the presence of titanium dioxide while they are circulating inside a reactor formed by a hollow space of not more than 5 cm of thickness, whose inner wall is the wall of a lamp emitting at least a fraction of its radiations with a wavelength shorter than 400 nm.In this reactor a cooling sheath is not provided between the lamp and the reaction mixture and temperature control is accomplished by means of the circulation of the same reaction mixture inside the reactor.
    Type: Grant
    Filed: October 8, 1992
    Date of Patent: January 4, 1994
    Assignee: Eniricerche S.p.A.
    Inventors: Fausto Miano, Enrico Borgarello
  • Process for the regeneration of active carbon
    Patent number: 5266540
    Abstract: The regeneration of active carbon onto which one or more organic substances may be adsorbed is achieved by means of a photodegrading process catalyzed by a semiconductor.
    Type: Grant
    Filed: March 22, 1993
    Date of Patent: November 30, 1993
    Assignee: Eniricerche S.p.A.
    Inventors: Roberto Menicagli, Fausto Miano, Enrico Borgarello
  • Method for the heterogeneous catalytic photodegradation of pollutants
    Patent number: 5053136
    Abstract: A method for purifying water containing pollutant mixtures is described, which uses a reactor containing a semiconductor as reaction catalyst and a lamp which emits radiation having a wavelength of less than 400 nm. The reactor, characterized in that its walls allow water and the pollutant substances to pass through, is immersed in the water to be purified so that the pollutants contained in it reach the reactor interior where they are adsorbed on the semiconductor activated by light radiation, and are then degraded.
