  • Patent number: 5627353
    Abstract: Spheres with a tetrahedral, octahedral and icosohedral geometry containing active compounds, wherein the spheres embrace the same volume as the fullerenes of the same symmetry, and are described by the formulas C.sub.360 N.sub.240 O.sub.24 U.sub.12, C.sub.1080 H.sub.300 N.sub.120 O.sub.24 U.sub.12, C.sub.144 N.sub.96 Cu.sub.14 and C.sub.432 H.sub.132 N.sub.48, their synthesis, the method of liberating the active compounds by irradiating the spheres to destroy the spheres such to release the active compounds, as well as possible uses for spheres filled with active compounds.

  • Patent number: 5480524
    Abstract: The present invention relates to a method and pertinent apparatus for purifying gases, exhaust gases, vapors, and brines, which are contaminated with undesirable chemical substances or contain high concentrations of these substances, by means of photocatalytic reactions occurring on the surface of catalysts.The catalysts are situated in a fixed or fluidized bed on catalyst carriers. In fluidized beds, the catalysts themselves can serve as catalyst carriers. The substrates to be purified are fed through a closed system which contains the catalyst carriers and catalysts.In the fixed-bed catalytic method, the catalyst carrier/catalyst system continuously or discontinuously passes through a washing zone to remove the generated mineralization products. The reaction is induced by shortwave photons of wavelengths between 250 and 400 nm.

  • Patent number: 4595575
    Abstract: The invention relates to a process for the continuous wet or wet-catalytic purification of waste gases by adsorption and chemisorption of the gaseous pollutants on activated carbons with simultaneous desorption of these pollutants or their reaction products. The process is carried out at 100 to 800 times gravity acceleration in a centrifugal filter, in the rotor of which a bed of fine-grain or fibrous activated carbon is arranged. The waste gas passes through this bed in codirectional or counter-current flow to the wash liquid. The pollutants are washed out with the desorbent flowing from the center outwardly.
