  • 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: 20190023568
    Abstract: The invention relates to known catalysts which contain cerium or other catalytically active components for producing chlorine by means of a catalytic gas phase oxidation of hydrogen chloride with oxygen. A catalyst material is described for producing chlorine by means of a catalytic gas phase oxidation of hydrogen chloride with oxygen, wherein the catalyst comprises at least oxide compounds of the cerium as active components and zirconium dioxide microparticles as the carrier components, and the catalyst is characterized by a particularly high yield, measured in kgCl2/kgKA T·h, based on the mass of the catalyst.

  • Patent number: 8392374
    Abstract: In an embodiment, a first row of data is stored in a database. The first row of data is hidden until a current date is later than a hidden expiration date. An indication is returned, to a requestor, that the first row does not exist in response to a query from the requestor that specifies a key that identifies the first row if the current date is before the hidden expiration date. The first row is returned, to the requestor, in response to the query if the current date is after the hidden expiration date.

  • Patent number: 8108367
    Abstract: In an embodiment, a constraint is created for a database table. The constraint specifies a condition for a first column in the database table and an action. The action specifies whether data that violates the condition is allowed to be stored in the first column. A value and a specification of a second column in the database table are received from a data source. If the second column is identical to the first column, the value violates the condition, and the action specifies that data that violates the condition is allowed to be stored, the value is stored in a row in the database, the row is marked as hidden, and an identification of the constraint that was violated is stored in the row. A query does not return the row that is marked as hidden.

  • Publication number: 20080172420
    Abstract: A method, system and computer-readable medium are presented for scoring the health of a database file. In a preferred embodiment, the method includes the steps of: retrieving a plurality of file attributes from a file in a database; determining if at least one of the file attributes is damaged; and creating a health score for the file based on what percentage of the file attributes for the file are damaged.

  • Publication number: 20030077206
    Abstract: A reactor and a process for carrying out parallel reactions on solids is described. The reactor comprises at least a sample holder block (1) with a multiplicity of reaction vessels (2a-2k), a heated support structure (3) and a cover (8, 9, 10) sealing all the reaction vessels (2a-2k). The cover (8, 9, 10) contains feed lines (4a-4k) and discharge lines (5a-5k) to each sample vessel (2a-2k). The feed lines (4a-4k) and/or the discharge lines (5a-5k) are joined together by means of feed and discharge channels (7, 8) running crosswise to said lines. The feed and discharge channels (7, 8) end in main fluid feed lines (11) and discharge lines (12).
