  • Process for purifying fluids
    Patent number: 10058814
    Abstract: A process removes substances from fluids, especially from exhaust gases of combustion plants, by contacting the fluid to be purified with Puzzolanes that contain at least 5% by weight of silicon and/or aluminum-compounds. These compounds can be dissolved away under the conditions prevailing during purification, such that they are excavated from the Puzzolanes.
    Type: Grant
    Filed: September 22, 2015
    Date of Patent: August 28, 2018
    Inventors: Michael Fichtel, Roland Fichtel

  • Modified trass and process for its preparation
    Patent number: 9597654
    Abstract: Modified Trass material has an enlarged active surface compared to native Trass. A method of preparation of the Modified Trass includes contacting Trass with an agent capable to dissolve away components in the Trass, and removing the dissolved components from the Trass. The modified Tass can be used for removing substances from fluids, in particular from exhaust gases of combustion plants.
