  • Publication number: 20210154657
    Abstract: A process is described for regenerating a catalyst comprising ruthenium or ruthenium compounds, which has been poisoned by sulfur compounds, in which the catalyst, optionally at elevated temperature, is subjected to treatment with a hydrogen halide, particularly a gas stream comprising hydrogen chloride, under non-oxidative conditions and additionally, optionally at reduced temperature, to an at least two-stage oxidative post-treatment.

  • Publication number: 20200208283
    Abstract: The invention relates to a gas diffusion electrode for reducing carbon dioxide, having a special catalyst morphology (silver in the form of agglomerated nanoparticles having a BET surface area of at least 2 m2/g), and to an electrolysis device. The gas diffusion electrode comprises at least one carrier and a porous coating on the basis of an electrochemically active porous silver catalyst and a hydrophobic material. The invention further relates to a production method for the gas diffusion electrode and to the use thereof as a carbon dioxide GDE in e.g. chlorine electrolysis.

  • Publication number: 20190210875
    Abstract: The invention relates to a method for the production of chlorine by means of photocatalytic oxidation of gaseous hydrogen chloride with oxygen as an oxidizing agent, in which the reaction is started on the surface of a photocatalyst by the action of UV radiation in a selective energy range.

  • Publication number: 20040050523
    Abstract: A process for transforming a metal alloy (28) having a liquidus temperature and a solidus temperature into a part solid/part liquid shaped body. The metal alloy (28) is poured in the molten state at a temperature (TMo) into a mould (10) having an essentially cylindrical mould wall (12), whereby the mould (10) at the start of filling exhibits a starting temperature that lies below the liquidus temperature, the mould (10) is set into an eccentric rotational movement at a starting temperature for the metal alloy (28) lying above the liquidus temperature and the rotational movement maintained until the metal alloy (28) has cooled to a to a discharging temperature lying between the liquidus temperature and the solidus temperature corresponding to a desired solid/liquid ratio in the shaped body and the shaped body removed from the mould (10) at the discharging temperature.

  • Patent number: 4881958
    Abstract: An adsorption device for gas separation with an adsorbent includes a thermally insulated container. Adsorber tubes with a given length are vertically disposed in the container for receiving adsorbent. A heating device is adjacent the adsorber tubes. Cooling tubes are disposed alongside the adsorber tubes and extend over substantially all of the given length for receiving coolant. A gas circulation device in the container generates a gas flow encompassing the heating device, the cooling tubes and all of the given length of the adsorber tubes.
