  • Method for cleaning viscose production off-gases and catalysts for use in the method
    Patent number: 11198093
    Abstract: A method for cleaning an off-gas from viscose production, essentially containing H2S and CS2, comprises passing the gas through a catalytic reactor containing a direct oxidation type catalyst, such as V2O5 on silica, to convert H2S in the gas to elemental sulfur, SO2 or mixtures thereof, either via the oxygen present in the gas or via oxygen added to the gas stream. Elemental sulfur and SO2 are removed from the effluent gas from the catalytic reactor, and the unconverted CS2 is recycled to the viscose production process.
    Type: Grant
    Filed: September 11, 2017
    Date of Patent: December 14, 2021
    Assignee: HALDOR TOPSØE A/S
    Inventors: Niklas Bengt Jakobsson, Peter Bo Olsen, Per Aggerholm Sørensen, Anders Theilgaard Madsen
